This has been going on for so long I've lost track of it. We potty trained DS1 at 2.5 years old and it took a while but we got there. He's now 4 (5 in July) and almost every time he goes for a wee he's dribbled a bit in his pants. He also has no ability to hold it for longer than a minute, absolute max. This has been going on for easily a year, if not longer, on and off. It's driving me mad! Any advice or tips?
