DS was EBF until a couple of weeks ago when I started giving him a formula feed in the evening on the advice of the HV. On Sat I went out for the evening and fed him before I went and then again at 10 am on Sunday - between this he had 2 formula feeds instead of one - and then fed as normal for the rest of the day and when he woke in the night and first thing this morning. However for his second feed this morning I had to resort to formula because when I tried to feed him he sucked a few times then screamed and refused to feed anymore even though he was hungry and I tried both breasts. I'm worried now that there's something wrong with my milk or supply and that I've messed up by having 12 hours break.
I tried to get him to feed just now but he's refused and is very much a baby who won't feed unless hungry.
what can I do?
