My DS is five and started full time education in a mainstream school, the main issue is that he's so picky with his food that I need help coming up with ideas. He dislikes bread, won't touch it at all, so sandwiches are a no go area, I've resorted to putting turkey slices in a bag, instead of in bread now but at least he'll eat it. Everything has to be cut up , so burgers, fish cutlets, all have to be cut into tiny pieces, even fish fingers are too big for his liking, he doesn't like vegetables but I always put them in his lunch. He has trouble with dipping food into things, so although he likes cheese, he's more likely to pour it all over himself then dip food into it.
So a regular packed lunch for him would be
Plain waffles (which he loves)
Turkey slices (will eat 90% of the time)
cut up meat/fish (depends on his mood)
vegetable or fruit (will always leave)
water (dislikes juice and will only drink milk in the morning)
I desperately need some new ideas.
