On our NNU, parents are actively encouraged to become involved in feeding their baby as soon as they feel ready and, for many, this will involve learning how to tube feed. Some preterm babies remain on the NNU solely because they are unable to take all of their feeds orally and need nasogastric feeds to supplement their nutritional requirements until they are mature enough to do so. For some babies and families this may take many weeks. Early discharge home of stable preterm infants still requiring some nasogastric feeds has the benefit of uniting families sooner and allows a more consistent approach to feeding by parents. Reducing the length of stay in hospital for preterm infants has been suggested to have emotional and psychological benefits for the family and for the infant’s development (1). Home tube feeding programmes have also been associated with successful weight gain and infants have not required readmission related to tube feeding (2, 3, 4). To ensure successful home tube feeding, parents need to be competent, confident, committed and well supported by community health professionals experienced in this area. On our NNU, any baby fulfilling the criteria in the Early Discharge guideline will be considered (5). Tube feeding at home could be an increased burden for some families and there is the possibility of complications relating to the tube feeding. Some parents choose not to take their baby home partially tube fed, preferring them to remain on the NNU until oral feeding is fully established. In our experience, however, most parents do choose to take their baby home early to continue to establish oral feeds (6).

This is a case report of a preterm infant who was discharged home early to continue to establish breastfeeding. Case study Baby D was born at 34 weeks gestation weighing 1.628kg (2nd to 9th centile). He was born by elective caesarean section for intrauterine growth retardation and placental insufficiency. He did not require any resuscitation at birth and was transferred to the NNU to start intravenous fluids. On the NNU, our aim is to support mothers to express their milk within two hours of birth. Midwifery staff explained the benefits of breast milk to Baby D’s mother, to encourage her to express her milk and she was shown how to hand express as it was her intention to breastfeed. By day six of life, Baby D had established full feeds via nasogastric tube using his mothers’ breast milk and he tolerated this well. Vitamin and iron supplements were started. As well as tube feeds, baby D was beginning to try and feed from the breast. His mother had been expressing regularly and had established a good milk supply, sufficient to support exclusive breastfeeding. Baby D was then transferred to Transitional Care. Transitional Care is part of the unit that enables mothers to stay with their babies and, with the support from neonatal staff, learn how to feed and care for their baby. This would include continuing to learn to tube feed and pass a nasogastric tube if early discharge was being considered. Baby D was discussed as part of the weekly Multidisciplinary Team (MDT) NHDmag.com November 2014 - Issue 99

preterm infant feeding: case sutdy sleepy but did have periods when he was awake and alert. He was still having full nasogastric tube feeds. He was nine days old. His weight was 1.55kg. To help the transition from tube feeding to breastfeeding, a ‘Top Up’ plan is used. This helps to assess whether a tube top up is needed. The Top Up plan is based on the quality, as well as the time of breastfeeds and it also helps to continue to support growth during the transition process. Baby D was 13 days old the next time he was seen with his mother and was observed feeding at the breast. His mother was using a nipple shield which helped baby D achieve and maintain an effective latch at the breast. He demonstrated competent feeding skills, limBy ceejayoz (www.flickr.com/photos/ceejayoz/3579010939/) (GFDL (www.gnu.org/copyleft/ ited only by his energy reserve.
