So I am just wondering... I am breastfeeding but have given bub a bottle of formula twice and when I do she completely zonks it and will sleep for hours (7.5 hours lastnight). She doesn't do this after breastfeeding even after giving her EBM where I know she has had the same amount if I was to give her formula. After breastfeeding at night she will sleep for about 5-6 hours after a lot of fussing and mucking around and during the day she doesnt sleep for long at all unless its on me. UGH! Hard work this stuff but I don't want to give up!
She has been putting on weight normally, quite a lot actually. But am just wondering why she does this? And any advice?
