I do not have much in the way in advise, but I did want to let you know that you are not alone out here. My son is now 12 years old and is still an extremely fussy eater. It started when he was 9 months old, he began rejecting table food, he too would throw up food and would only eat the pureed baby food up until he was two years old. When I finally took the baby food away, he would eat things like Lance Peanutbutter crackers, pretzels, chips, CRAP like that, but everything he ate was immediately followed by a drink to soften what ever he was eating in his mouth. He is still like that today. His main course of meal is French Fries, from whatever fast food place you stop at. He will eat dry cereal, fruit loops (with a milk in a sippy cup on the side, the only way I can get milk in him is through that sippy cup) and cheerios with a glass of OJ. He still only eats crackers, chips, pretzels and apples. He has never eaten meat, never had a hot dog, never had pizza, has never sat down at Thanksgiving and eaten a meal. He is growing and gaining weight, but he is also sick alot with colds and things and he is ADHD. He is extremely athletic. The doctors told me that he will eventually grow out of it, but I am still waiting. My advise to you is, DON'T WAIT. I fear his wedding will be catered by McDonalds. I beleive he has some type of eating disorder, that is complicated by PURE STUBBORNESS at this point, but how do you force feed a 12 year old. There are alot of people out there that will want to give you advise and tell you, "if he were mine, he wouldn't be eating, he would stave first, or if he didn't eat what I put in front of him, he wouldn't get anything at all." Well until these people walk a mile in your shoes, they have no idea how they would handle the situation, and as a mother, I truely doubt they would let their child starve. My advise to you since your baby is so young, I would have her checked out medically and get this addressed now and don't make the mistakes I did and assume they will grow out of it, because he is almost 13 and refuses to try anything new.
