Hi B.,
I just wanted to pop in and mention a few things about GERD (GASTRO-ESOPHAGEAL REFLUX). wHEN MY DAUGHTER WAS BORN, SHE WAS A CHRONICH PUKER. I work for the wic program and have done so, for about 12 1/2 years. Reflux in infants is fairly common and it usually clears up on its own. She was blessed by 10 months to refuse all baby food and was on complete table food, therefor eliminating the puke reflex......so I thought.
When she turned 12 months old, she started self induced vominting (putting her fingers down her throat, triggering the gag reflex and then puke) If the gag reflex is strong enough, you really don't have to work at puking. It just happens because this is something your body has learned to do.
I took her to one of her pediatricians and he decided, though she was small for her age, there was no medical problem (not loosing weight) SHE WAS JUST REACHING OUT FOR ATTENTION) tHAT WAS THE DIAGNOSIS FROM 1 DOCTOR. Next month different doctor, same diagnosis. I was really getting concerned by the 3 month of this. I took her again to another doctor at the clinic and now we have a medical problem because she is throwing up frequently, starting to refuse to eat and oh no, started losing weight. Well, surprise, surprise.... she had severe reflux(heartburn) and the only way she knew how to help the situation was by throwing up. If she threw up, all the acid would be removed and she would feel better.
I wanted to give you more info but I need to get back to work. I am not saying its not behavior.......but rule out all medical conditions before you except the lack of parenting skills being a problem.
If you think there is a problem, you know your children the best, keep going until yopu get an answer. If your doctor is of no help, request/demand to see a pediatric gastroenterologist. They specialize in children and digestive disorders. The testing is not alot of fun but neither is feeling sick half the day.
Good luck! I hope that reflux is all it is, that can be treated. If it does end up behavior.......good luck, theres even less help out there on this topic. I have investigated alot, my 12 year old has behavior issues and have had them since 4 years old. She has ADHD & oppositional defiance disorder. It took me a long time to find a doctor thta was educated enough to help. Then I moved across the country.
