Girls, I'm starting to panic? My little one is barely eating anything except for his breast. He might chew on cheese, apple, bread or drink some kefir (I know that milk is still not allowed, but I'm afraid he's hungry because he's not small anymore). Pancakes, omelets, soups, porridge used to eat before, two weeks ago he refused. As soon as he sees a spoon, he closes his mouth and turns away. Has anyone encountered such a situation, how to deal with it? I sit at the table with him, I give him food from my plate, he still doesn't want to. I don't force him, but I'm very worried about this.
