DS (3.10) has been out of nappies for about 18 months now, and is really good at using the toilet. However, over the last few weeks, he has started needing to go for wees all the time, but when he keeps saying he needs to go, it can be just a few drops. If you try to tell him he can't possibly need another wee, then he gets upset. He says he doesn't have any pain, and is fit and well, but is this a normal thing kids do, or should I be checking it out. He was at the GP a few weeks ago for a bad cough, but is over that now, and is as bright as a button. Is it just a phase??
