I just realized this was written a year and a half ago, so I will just send it any way and hope you are having fun with your son. This request was in the "spotlight" so I thought it was recently. duh
I would try foods he can feed himself, not liquedy baby food. I have a now 1 yr old and at 9 months he really started loving feeding himself. I still try to feed him stage 2 baby food for veggies, but for the most part, he now likes to feed himself. You can give him anything but penuts, honey, egg whites, raisins and any other food that may cause an allergy or choking, you probably already know that. I loved it when he turned 9 months.. He was much more independent in eating, playing etc. He now wieghts 26 pounds a 1 yr, so it is obvious he loves to eat.
When I first read your request, the first thing I thought of telling you was a baby story of mine that my mom told me. So it is no advice but similar... I was about 7-8-9 months old and I started doing exactly as your son does, spitting and spraying everthing I ate I would aim for my moms face... so my mom became so frustrated and didn't know what to do, she asked her mother for advice. She (my grandma) said to "take a bite and spit it right back in her face, give her a taste of her own medicine, that will teach her"... so my mom did exactly that, and I thought it was the funniest thing in the world! My mom told me she had never heard a baby laugh so hard and in turn, she could not stop laughing. But it was the worst advice she got, so dont do that. Just kidding. I guess I just grew out of it, because my mom just ignored me every time after that.
So good luck!
