Poppy is very nearly 4 months. She was exclusively BF for the first 4 weeks but due to problems with thrush she is now BF and FF. Poppy is very grouchy most of the time, unless we are out (she is very high maintenance). I'm worried she is grouchy because she is hungry. She has formula at 8pm, 2am and 7am (she has boob before all of these feeds and is topped up with formula (she drinks anything from 4oz to 7oz after boob) she also has formula at 3pm and spends most of the day on the boob inbetween feeds. Is she hungry?? I've tried expressing but only get about 2oz and thats trying both boobs. I don't really want to up the formula intake as I really dont want her to stop BF and I think she will if I up the formula, what else can I do?? Please help.
