Having a little hard time getting my son to want to eat solids! He's so ready to eat whatever when he's in my lap and I'm eating but when I put him in his high chair he does not care to eat what I have for him. If he smiles and I put it in his mouth he swallows it but doesn't go opening his mouth for more hahaha help 😅
