My 16 month old had suddenly started to refuse some meals or eat only a few mouthfuls or at best half of her meals over the last few days. She only has 2 x 6oz bottles per day now and usually formula on her porridge but refusing her porridge now. Doesn't seem to be evidently ill though and will eat fruit fine and biscuits but everything else she is suddenly fussy with. Anyone any idea what's going on?!
