Myy DD is 16 months and has always eaten such a healthy diet. She had a virus a while ago and understandably went off her food. But, now she's better she won't eat anything other than crisps. I'll cook for her and she pushes good food away, but if she sees me eating crisps or a biscuit, she wants it! I don't think her appetite has gone anymore, I think she just wants to play up so she can be given crap... What do I do?
