Key points

  • Babies born early, or born to term with medical difficulties, are at risk of feeding and communication difficulties in the early period as well as in the longer term.
  • The number of babies admitted to a neonatal unit has seen an increasing trend due to advances in health care expertise and technology.
  • The neonatal unit is a stressful environment which can impact babies’ development.

Role of speech and language therapy in neonatal care

Babies admitted to neonatal units are at risk of feeding and early communication difficulties. This is due to being born early or having complex medical conditions that affect their neurology and development, and/or functioning of the structures required for sucking and swallowing.

The speech and language therapist (SLT) has a role in identifying babies at risk of feeding or communication difficulties and in helping babies and their families to establish safe and positive oral feeding, and support their language development.

The SLT also has a role in education and implementation of developmental care on the neonatal unit as part of the wider team to support babies’ optimal neurodevelopment.

Babies may spend time on a neonatal unit if they are born prematurely, unwell, with brain trauma, or require other medical intervention.

The definition of a premature baby is when they are born before 37 weeks gestation.

Premature babies are grouped according to their gestational age:

  • Extremely preterm (born <28 weeks)
  • Very preterm (born 28-32 weeks)
  • Moderate to late preterm (born 32-37 weeks)

Babies may also spend time on a neonatal unit if they are born at a low birth weight. Low birth weight can be caused by prematurity, or being small for gestational age.

Definitions of low birth weight (Tucker and McGuire, 2004):

  • Low birth weight: <2500g
  • Very low birth weight: <1500g
  • Extremely low birth weight: <1000g

Different levels of neonatal care

Level 1 Special Care Baby Unit (SCBU): Babies who need monitoring of their breathing or heart rate, need oxygen support or additional tube feeding, or are undergoing treatment for neonatal jaundice, may spend time on a SCBU.

Level 2 Local Neonatal Unit (LNU): Babies who need intensive care support short term, including receiving respiratory support, such as continuous positive airway pressure (CPAP), or high flow nasal cannula oxygen, as well as babies receiving parenteral nutrition, such as through an IV line, may need this level of care.

Level 3 Neonatal Intensive Care Unit (NICU): Babies who are born before 28 weeks gestation or weigh less than 1000g, babies with brain trauma, and those needing ventilation or a high level of CPAP may spend time in a NICU. Babies who have severe breathing or gut disease or those requiring surgery may also need this level of care.

Babies that spend time on a NICU may receive the following:

  • Intensive care: This is the level of care provided for the most unwell or unstable babies that have the greatest needs in terms of staff-to-patient ratio.
  • High dependency care: This level of care is for babies who still have high needs and require access to highly-skilled staff, but do not require intensive care.
  • Special care: This is the level of care provided for babies who require additional care delivered by the neonatal service but do not require either intensive or high dependency care.
  • Transitional care: This is for when babies are almost ready to go home. Mothers may be residents with their babies in transitional care and providing care. A baby may move to transitional care after spending time on a high level unit, or may only spend time in transitional care (such as babies having phototherapy).

Descriptions of levels of neonatal care can be found in the British Association of Perinatal Medicine Categories of Care guidance.

Vulnerability and risks

There are many reasons why a baby may be born prematurely or become unwell during pregnancy, birth, or shortly after birth. In particular, there are certain risk factors that predispose a pregnant person to go into premature labour, as well as known causes (Institute of Medicine, 2007).

The risk of health complications occurring is higher:

  • The earlier the baby is born
  • The lower the weight in relation to gestational birth age
  • The more unwell the baby is

Babies born prematurely or unwell are vulnerable to complications including:

  • Feeding difficulties
  • Breathing difficulties
  • Heart problems
  • Neurological injury
  • Gut problems
  • Structural problems
  • Developmental difficulties, including speech, language and communication difficulties

Premature babies are also at risk of having problems with:

  • Temperature regulation
  • Metabolism
  • Immunity
  • Hearing and vision
  • Sensory processing difficulties
  • Chronic health problems

Wider impacts include:

  • Educational outcomes
  • Psychosocial issues
  • Impact on families

Feeding difficulties

Feeding is a complex skill for all babies. Babies born early are developing oral feeding skills at a time of significant growth and brain development. Feeding is impacted by immaturity of motor pathways for sucking, swallowing and breathing; development of the gut, developing physiological and state regulation and development of motor and sensory pathways in the brain (Gewolb et al, 1999; Jadcherla, 2016).

Babies with complex needs are at risk of persistent feeding difficulties and potentially the need for longer term alternative feeding methods (Harding et al, 2015; Hawdon et al, 2000).

Risk factors associated with poorer feeding outcomes of ex-premature babies:

  • Extreme prematurity
  • Extremely low birth weight
  • Delayed/disordered oral motor skills at term age
  • Breathing problems needing breathing support for longer
  • History of necrotising enterocolitis (NEC) (where the tissue in the gut becomes inflamed and starts to die)
  • Longer time transitioning from tube to oral feeds
  • Medical conditions impacting on feeding eg neurological, heart, sensory, or gut issues

Ex-premature or unwell babies are at risk of longer-term feeding difficulties that include:

  • Difficulties using oral motor skills effectively for adequate intake of nutrition
  • Fussy eating or refusal
  • Swallowing difficulties
  • Increased vomiting
  • Difficulties with transitioning to solid foods
  • Increased stress on families and parent-baby relationships in the longer-term
  • Longer term tube use, which can lead to long term eating problems; reduced parent-child interaction opportunities; missed critical periods for taste and texture; impaired feelings of satiation; oral aversive behaviours, and potential impact on oral motor development

Breathing difficulties

Premature babies may have difficulties breathing after birth, due to an underdeveloped respiratory system. The lungs of a premature baby at birth may lack ‘surfactant’, which is a substance produced by the body to allow the lungs to expand and contract.

Term babies with traumatic birth are also at risk of developing breathing difficulties called ‘respiratory distress syndrome’ needing some form of support such as mechanical ventilation, continuous positive airway pressure (CPAP), or oxygen delivered via nasal prongs.  Further information is available via the RCSLT feeding and non-invasive respiratory support position paper.

In the majority of cases, respiratory distress syndrome can be effectively treated; however, some babies may also develop longer-term breathing problems called ‘chronic lung disease’.

Breathing difficulties may have an impact on the development of oral feeding for babies, including:

  • Delayed introduction of oral feeding due to high levels of support needed.
  • Difficulties coordinating sucking, swallowing and breathing during feeding.
  • Reduced endurance, with increased effort needed for oral feeding.
  • Risk of negative experiences around the face and mouth due to breathing support (Wood et al, 2003; Jadcherla et al, 2010, Ferrara, L et al, 2017).


Heart problems

Congenital heart disease in babies may exist in isolation, or alongside a chromosomal change or a syndrome (Jadcherla, 2016). Infants born prematurely, especially those born extremely preterm have higher blood pressure than term infants. Babies with chronic lung disease are at higher risk of heart problems.

The most common congenital heart diseases in premature babies include ‘patent ductus arteriosus’ (PDA) (a persistent opening between the two major blood vessels leading from the heart), ‘ventricular septal defect’ (VSD) (a hole in the wall that separates the two lower chambers of the heart) and ‘atrial septal defect’ (ASD) (a hole in the wall that separates the two upper chambers of the heart). All heart conditions will impact how effectively the heart is able to pump blood around the body. If untreated, they may cause the baby to go into heart failure.

Congenital heart disease may have an impact on the development of oral feeding for babies, including:

  • Delayed introduction of oral feeding due to instability or medical interventions.
  • Reduced tolerance of feeds due to poor gut perfusion.
  • Poor growth and nutrition due to increased nutritional requirements.
  • Increased stress associated with feeding which may impact longer term relationships with eating/drinking.
  • Post-surgery or intubation complications impacting the upper airway and swallow.
  • Associated problems that may occur alongside congenital heart disease and have an impact on the baby’s oral feeding skills.

Neurological injury

The brain of an unborn baby develops rapidly in utero. A baby that is born prematurely is at risk of neurological injury after birth. Neurological injury may include intraventricular haemorrhage (IVH) (bleeding in the brain) or periventricular leukomalacia (PVL) (softening of white brain tissue).

There is increased risk of developmental delay as the severity of injury increases. There is an increased risk of speech, language and communication problems, specifically for babies with PVL grade III/IV and IVH, including moderate-severe language disorders.

Hypoxic ischemic encephalopathy (HIE) is a condition that affects how a baby’s brain functions. It is caused by a reduction in supply of oxygen and blood to the brain and other organs during the time of birth. Lack of oxygen to the brain can lead to brain injury, which may be categorised as mild, moderate or severe.

Babies with moderate to severe HIE in the neonatal period may present with difficulties in muscle control, state and alertness, and sucking and swallowing coordination. The longer-term impact of HIE may include developmental delay, cognitive and neurodevelopmental delays, epilepsy, and motor delay (Shankaran 2014).

Neurological injury in babies may lead to longer term neurodevelopmental impairments. Data from EPICure studies show that the prevalence of neurodevelopmental impairment was associated with the gestation of premature babies, with greater prevalence of impairment the shorter the gestation (45% at 22-23 weeks, 30% at 24 weeks, 25% at 25 weeks and 20% at 26 weeks) (Moore et al, 2012).

Neurological injury may have an impact on oral feeding and communication development for premature babies, including:

  • Impaired motor and sensory control of the muscles required for coordination of sucking, swallowing and breathing during feeding.
  • Increased risk of aspiration of fluid to the lungs.

Longer term neurodevelopmental and neurological impairments in premature babies may also impact their:

  • Speech, language and communication development
  • Motor skill development
  • Learning abilities
  • Sensory processing
  • Attention and behaviour

Gut problems

Premature babies may experience gastro-oesophageal reflux (GORD). Reflux occurs when partially-digested milk passes from the stomach back into the oesophagus and sometimes into the mouth. The acid from the stomach may make this uncomfortable and painful for babies.

Premature babies are also more likely to have an immature gut, putting them at risk of complications such as necrotising enterocolitis (NEC). NEC is the most common gut problem in the premature population. The risk of NEC is related to the gestational age and weight of a baby. The younger the gestation and smaller the weight at birth, the higher the risk of NEC (Thompson and Bizzaro, 2008).

NEC can be associated with other long term conditions, such as ‘short gut syndrome’ (lack of a functional small intestine), which can also affect term babies. In extreme cases, NEC can cause multi-system failure and death in babies.

Gut problems may impact oral feeding development for babies, including:

  • Delayed or interrupted introduction of feeds
  • Pain and discomfort with feeding
  • Negative associations with feeding leading to refusal or reduced acceptance
  • Swallowing difficulties

Structural problems

Anatomical differences in the structures of the head and neck, which could happen either in utero or after birth, may affect an infant’s ability to suck, swallow and breathe safely and effectively. This increases the risk of aspiration (fluid entering the airway or lungs) and poor growth.

Abnormalities of the head and neck anatomy present at birth occur during certain stages of development in utero. Some are identified during routine pregnancy scans, others are not evident until the infant is examined after birth. These abnormalities include:

  • Choanal atresia (narrowing of the nasal passages)
  • Cleft lip and/or palate
  • Micrognathia (small jaw) which may be isolated or associated with a syndrome
  • Laryngomalacia (floppy upper airway)
  • Laryngeal cleft (abnormal opening between the voice box and oesophagus)
  • Upper airway obstruction or subglottic stenosis (narrowing of the airway)
  • Vocal fold paralysis
  • Tracheoesophageal fistula (opening between the airway and the oesophagus)
  • Oesophageal atresia (the upper part of the oesophagus is not connected to the stomach)
  • Abnormalities in blood vessels
  • Presence of a tracheostomy (an opening created at the front of the neck to help the baby breathe)

Structural difficulties caused by trauma occur mostly after surgery or intubation. It may at times involve bruising or damage to a nerve. The most commonly seen are airway swelling post extubation, subglottic stenosis and vocal fold paralysis.

Anatomical abnormalities may have an impact on the development of oral feeding for babies, including:

  • Poor suction during sucking leading to slow or inefficient feeding.
  • Increased risk of aspiration of fluid into the airway due to ineffective protection.
  • Poor coordination of the suck, swallow, breathe sequence due to an interruption in airflow.

Developmental and speech, language and communication difficulties

Babies born prematurely are at risk of experiencing developmental delays, including language and communication. This risk increases with lower gestational age and lower birth weight of the baby (Kerstjens et al, 2013; Guellec et al, 2001).

The neonatal unit environment can also be stressful and babies in hospital have reduced exposure to language and developmental stimulation. Communication difficulties could also be associated with brain damage that the baby may experience at birth (Limperopoulos et al, 2007).

Developmental and communication difficulties experienced by the premature baby, or those with neurological damage may include:

  • Movement difficulties
  • Delay in reaching milestones
  • Attention difficulties
  • Cognitive difficulties
  • Sensory processing difficulties
  • Difficulties with understanding language
  • Expressive language difficulties
  • Social interaction difficulties

Educational outcomes, psychosocial issues and impact on families

Educational outcomes

The EPICure studies have shown that extreme preterm children have persistent communication and cognition difficulties that have an impact on their access to the national curriculum into school age.

A study looking at the educational outcomes of the extreme preterm population at age 11 found that these children had poorer performance than their classmates across all national curriculum subjects, with the most prominent difficulties in maths, and around age 2/3 had some degree of special educational needs (Johnson et al, 2009).

Psychosocial issues

The neonatal unit is a stressful environment for vulnerable preterm and medically fragile infants. Preterm and sick infants are exposed to multiple potential stressors in the neonatal environment, including the daily routines that are necessary for the infant’s medical care.

Current research is now paying closer attention to the impact of adverse childhood experiences on an individual’s emotional and psychosocial development. Studies show that prolonged activation of stress hormones (toxic stress) in infancy can reduce neural connections at a point where new pathways should be forming, therefore altering brain structure and function (Smith et al, 2011). The practice of ‘developmental care’ focuses on reducing exposure to this stressful environment, by providing neonatal care that is nurturing, stable, and engaging.

Impact on families

Having an infant that is born early or unwell and needing to spend time on a neonatal unit is difficult for families and can cause high levels of anxiety and stress (Agaard et al, 2008).

The experience of having a preterm or sick infant can impact on a parent’s ability to take on their parenting role (Flacking et al, 2006) and has an impact on their interactions with their infants, not only on the neonatal unit, but also when discharged home (Forcada-Gues et al, 2006).

Family-centred/family-integrated care places parents at the centre of their babies’ care, and has been shown to have a positive impact on families as it:

  • Reduces babies’ stress levels
  • Promotes better health and reduces length of stay in hospital
  • Helps parents to bond with their baby
  • Improves outcomes, both on the unit, and after discharge
