I'm trying to get LO to eat more solids and he is very much disinterested in the idea. Usually, he makes a horrified face and spits it out. Today, I was able to get him to eat some mango, kiwi, and strawberry but he just swallowed them whole. He doesn't try to chew or gum anything I put in his mouth. Is this normal? I'm scared to give him larger chunks (BLW style) because I think he will choke.
