T.B.
My daughter did this about the same age. Hers was an independence thing, she just wanted to feed herself and decided she no longer wanted the pureed food. I started giving her really soft cooked veggies that she could feed herself, and she gobbled them up. We pretty much went completely off the baby food at this age, and I just cut up all her food super small and let her have at it. I even would give her a cup of yogurt with a spoon and let her try her hand at that. Warning, this makes most mealtimes lead to a bath, but at least she was eating well. I also started cutting back the number of nursing sessions at this time so she would actually be hungry at mealtimes. She mastered the spoon really early since she had a lot of practice and does really well with most foods. Since she has been eating what we eat for so long, she is not picky at all and loves all fruits and veggies. People are always amazed at the foods she will eat. Just be creative and offer a lot of variety, eventually he will start eating more.
