My 6 year old goes through phases where she really doesn't like eating breakfast. She's normally a very good eater and not at all fussy but frequently in the mornings she says she's just not hungry. I don't want to have a battle over it and I clearly can't force her to eat but I hate the idea of her going to school without anything. I've tried offering her lots of choices and suggest she just have one small thing - but the last two days all that's resulted in is half of one of the small pots of petit filous. Is that enough? Don't kids who eat breakfast do better in school? Any advice?
