My DD is 20 weeks and was exclusively breastfed until around a month ago. I switched to formula with no problems, she would drain a 7oz bottle no problem. But the last few days she's drunk half, then gets fussy and I have to stop. She's still hungry though because she's sucking her hands and whingeing. And if I offer her boob she takes it.
I'm not sure what to do, should I offer her 4oz bottles more often instead of 7oz? I don't understand why she went from drinking more to stopping half way through. I still breastfeed her during the night, normally she only wakes once. Help appreciated!
