We are at the end of our tether with ds who is just 3 and will not eat! He has a good appetite but he does not like anything and his fussiness is getting worse and worse. It is usually food that he will not even taste because he says he doesn't like it. We do not make really complex food but do include a good range of meat, fruit and veg. We don't want to have to make him other food from us and 5 year old ds does not seem to have a problem at all. Advice please?!
