Who may be able to join
- Mothers who have delivered, preterm (before 34 weeks) infants who plan to express breast milk for their infant(s). Their infants will need to be less than 72 hours old prior to enrolment and likely to remain in NICUs for at least 10 days.

About this study
Official title: Randomised Trial Comparing the Efficacy of the ISIS Duo iQ Electric Breast Pump and the Medela Symphony Electric Breast Pump in Mothers Expressing Breast Milk for Preterm Infants
This is a randomised controlled trial investigating the performance of two, 'state of the art' electric breast pumps in mothers who have delivered preterm infants. The main data collection period will be up to day 10 post delivery data. Data collected will include a record of the weight of milk produced during the first 10 days and a short questionnaire to find the mothers' opinions of the pumps used. On Day 5 a timed and weighed expression of 15 minutes will be carried out. After the first 10 days, mothers will be asked to collect brief information on their continuing use of their pumps and subsequent duration of breast and bottle feeding, mothers will be contacted at 3 and 6 months post-term
