My fave story was of a boy whose mum didn't want to do med.s and spent a lot of time and effort changing his diet. She'd often come in and tell me some of the things she'd found he reacted badly to, and it wasn't just the 'usual' culprits. Her boy was a different kid when his diet changed. Having said that, when he got to his teenage years, he was much harder to monitor diet-wise (just wanted to fit in with his friends, understandably) and did end up going onto medication.
This is why GAPS is brilliant. Rather than managing symptoms with an elimination diet that can unhealthy and difficult to maintain long term, it treats the cause and heals the gut so that later on the person can eat those foods without consequences.

I think your plan to wait is good- do more research so you can make a decision you're happy with.
