Abstract
Breastfeeding initiation and continuation rates in Sunderland are significantly lower than the national percentage. In this trial, we investigate the effectiveness of encouraging the use of an online breastfeeding tool (the breastfeeding friend) on breastfeeding initiation and continuation rates among mothers in Sunderland.
