My 13 month DS was mostly BLW so he never let me feed him. Now the problem is he won't try new foods, especially veggies and meat. He will eat just about any carb or fruit, bu when it comes to veggies or meat he won't let it near his mouth. Is this just a phase? Should I keep offering even though it just goes on the floor? His iron was low so he's on iron supplements, which is super annoying.
