5 Yr old DS was potty trained pretty easily at about two and a half. For some reason - and I'm kicking myself now - we let him carry on wearing nappies at night. He's now 5 and won't sleep without them. We limit drinks after tea time to an inch of milk in a cup bit he regularly does so much wee at night it leaks. Over half term we've tried to wean him off nappies and he's done a few nights sleeping on those throw away absorbent sheets. But he's such a heavy sleeper he doesn't wake up when he's weeing, he just wakes up at 6am with the sheet soaked. I don't know where all this wee is coming from!! Tonight he's insisted on having a nappy back on. Does this mean he's just not ready? Or what are we doing wrong? Should we persist? Thanks in advance.
