Hello ? Such a problem, the child refuses to eat vegetables and soups. I made soup with potatoes, beef, rice, he ate it with pleasure, for the last month he starts to fuss, eats somehow, and then I cooked rabbit soup, he doesn't eat it. Maybe I throw too much meat, what doesn't like, I cooked broccoli with squash, he doesn't eat it, bought as soon as I started feeding him in jars of broccoli, he ate everything was ok, started cooking just broccoli without anything, so he doesn't eat it, and from the jar he doesn't eat anymore, already for more than a month we have something to allergy, rough red spots on feet were and cheeks
