RR, I am definitely not an expert. But I think that it could be possible that teething would predispose a child to ear infections - after all they do pull on their ears when teething. I also think that if he's 2 now and hasn't had constant ear infections (other than over a 2 month period) that they wouldn't think of grommets. I think that would be more the case if he had the infections constantly over a longer period, like 6 months. Sometimes when they get things a lot of times in the space of a couple of months it can mean that it didn't quite clear up in between. Also, it sounds like once those pesky teeth are all through he will be fine again. I hope he gets better for you soon.
