My sister has a two week old DS and has been advised by midwife to feed only one side at each feed. I've got two little ones but can't quite remember what I did - I'm sure I would have offered the other breast though too, if they seemed to want more - what does everyone do now?? There seems to be a lot of conflicting advice. My sister's DS ends up feeding for an hour or more on one side and she gets very sore and surely after a while a lot of that is not him sucking but just comfort ...
