Investigating the effect of domperidone on breast milk supply following preterm birth- the SUMMIT follow-up study

This is a long-term follow-up study for mothers and their premature babies who participated in the SUMMIT trial, which compared two doses of domperidone to increase breast milk supply. The aim of this follow-up is to understand the long-term effects of the two doses on how long breastfeeding continues, and on the child's growth and brain development up to 2 to 3 years of age. You are eligible to participate if you and your baby took part in the SUMMIT randomised trial. In that trial, you were the mother of a baby born before 34 weeks, experienced low milk supply between 7 and 28 days after birth, and were pumping at least 6 times per day. Participants are followed up with questionnaires and assessments about their child's feeding, growth, and neurodevelopment at key time points up to 24 to 36 months corrected age. This long-term data is important because it will show not just whether domperidone increased milk supply short-term, but whether any differences persist and ultimately benefit the child's health and development over the first years of life.
