breastfeeding is going really well but our 5 week old baby is not sleeping at night untill 3/5am and for most of this time she is sceaming. She takes her time when feeding and it takes its toll at night. My partner has suggested that he could do one of the night feeds so i can sleep and also she takes the bottle so much quicker than the breastfeeding, and i've heard that she might take in less air with a bottle which would stop her being too windy and uncomfortable and help her sleep. Problem is as I'm going back to uni one day a week and I am only able to express enough for that day there is not enough expressed breast milk for a night time feed - (finally i get to the point!!) - is it ok to introduce a formula feed and if so what is a good brand?
