I have a three week old baby who we think has silent reflux (midwife advised). We are seeing a paediatrician the midwife knows on Monday but just wanted to hear from other parents who have been through this. My baby cries after feeding and changing when we try to settle her. The midwife advised the use of a dummy to settle my baby to sleep and that helps. We are hoping to be given Ranitidine on Monday. How soon does it work? Is it something she will need to take for a while ? Any tips you can give we would appreciate. We changed the milk to lactose free a couple of days ago and have had more poo (as baby was constipated even after changing to comfort milk).
