We are very worried about our DS 20 months. He is pretty much refusing to eat the vast majority of his food, is losing weight, and producing pellet poos and concentrated wees. He is very independent and wilful (which in the long run I think is a good thing) and will not let us feed him. He is also bright, and by bright I mean he has been talking in sentences since 18 months (I want toast, I made poo, etc) amongst other things.
Please help us! He just will not eat what is put in front of him at dinner/lunch and just plays with it and throws it, and he usually won't eat replacements (e.g. toast) once he's rejected his dinner/lunch either. He is also clever enough to be able to find "hidden" vegetables/bits of meat and throw them out of his plate.
He usually eats his breakfast (weetabix or porridge) and he will usually eat apples, melons, any kind of soft fruit, baked beans and toast with butter or marmalade. And he will drink formula in the morning and evening (though not milk). But I really don't think that's an adequate diet and it certainly doesn't have enough protein in it.
Should we take him to the doctor? He weighs less now than he did two months ago, and he has really shot up height-wise in that time too.
