My daughter is formula fed and as always been brilliant when feeding. However for the past few weeks, feeding time is turning into a battleground. Shes currently on 6oz, which she takes fine for the first 3oz, then after stopping for winding, the nightmare begins. She often refuses to take the bottle back, she pushes it away with her tongue, tosses her head, pushes it away with her hand, arches her back, squirms, cries etc. Shes obviously hungry because she cries for the bottle back but has a mouthful then pushes it out again and repeats this process to sometimes finish the bottle. Feeding times can take up to and over an hour and leaves us both exhausted. Anyone else had similar problems?
