Hi my baby is 11 weeks old and I have just stopped breast feeding and moved to formula ( she has been combo feeding since birth ) and she is still only going for 2 hours between feeds apart from the first stretch at around ten which is 4 hours? I thought that formula fed babies were supposed to sleep for longer? I think the problem we have is she will only take a small amount of feed at a time 70-100 ml.. Anyone got any suggestions? It is taking us an hour to feed her each time to try and get more milk into her so by the time she is down she wakes in an hour!
