anyone got any tips on how to get your littles to eat healthy

we have a little in our system who is extremely picky and is extremely sensitive to textures
she won't eat fruit, because it makes her wet and she gets upset about it

she won't eat sweet things, because it makes her sticky and again, she'll make a seen

she won't eat fish, because it makes her smell weird and she doesn't like that

she won't eat cerial, because it tastes too dry, and with milk, it makes her wet

I can get her to eat chicken (as long as it has bread crumbs on), and she'll eat fries (though they make her dirty, she tends to just rub it on the table)

she also doesn't eat much (which I think is probably common among littles), though she is still in nappies and I think part of it is that she doesn't like filling them (I know, gross)

we just really want to help her

she can't live off breaded chicken and fries. more to the point, we really need to get her used to things (without actually forcing them on her)
