Not sure what to do. He used to eat anything and everything, but now refuses most things. He'll religiously eat a bowl of weetabix and banana for breakfast, but now refuses nearly all lunches and dinners. He'll happily eat a croissant, flapjack, cheese and most fruit, but nothing substantial. Throws all lunches and dinners on the floor and won't let me get more than a few mouthfuls in if I feed it to him. It's been going on a while now and I'm getting concerned. He still breastfeeds so that reassures me a tiny bit, but he's not eating anything substantial. I feed him all healthy homecooked meals like fish, chicken etc, which he used to love but hardly touches now. What do I do?
