cherylaw, she may have food texture issues. A 7 year old can say she likes something, just to say it, but in fact have a real distaste for it.
What does she eat at her mother's house?
I think if she doesn't want to eat whatever is for dinner, bread is fine.
Relax the rules let her eat what she wants to when she wants to its okay isnt it, and if she wants a snack later ,wheres the harm in that ,keep healthy food in then thats what she will snack on,. Make sure she has fun and enjoys her time with you, games and get dad involved with her playing sports and outside activities, focus on her positive side and praise her when you see her doing something right
We had that problem also a while back. Try this: if she won't eat what you've made and you know she likes it, put it in the fridge and pull it out later when she says she's hungry. Don't give in to the junk food. My kids aren't that keen on many vegetable, so if I make something I know they don't like, I will cut up an apple for them, or some grapes on the side instead of veggies.
