For the past week week my 6wo has been sleeping more and taking less formula. She was having 3oz and often 4oz throughout the day but now is just taking 2oz. That is often a struggle to force her to take it. Last night and this morning she has taken 1oz! Argh!! She will wake up 3 or 4 hourly crying for her feed and is ravenous at first but eventually come to a stop So we wind her change her and she either falls straight back to sleep or has her awake period but refuses to take more. She is having wet and poo nappies throughout the day and is perfectly content and happy! Should I be worried?!
