I had a very similar situation with my son who is now almost 15 months. He would not eat any solids to the point where he would just gag and throw up if I put ANYTHING in his mouth other than breastmilk from the tap. When he was about 9 & 1/2 months I convinced my pedi that we needed some help so we went to a pediatric speech pathologist. She was very quick to figure out what his problem was and it turned out that he had a hypersensitive gag reflex and took a very long time to get used to foods. He was pretty much exclusively breast fed for 10 months. His weight was never an issue, but he did become severely anemic from an iron deficiency. Perhaps a speech path can help you out too. I wouldn't say my son is normal now, but he's much better and he is no longer anemic. It's also probably a good idea to supplement with a multi-vitamin since most contain iron. Good luck!
