DS is 2y10m and we did potty training very successfully about a month ago. Straight away his night nappies were dry too, so I took the plunge and stopped using nappies at night. Everything was fine for the first fortnight, but now he has wet the bed every night for 5nights. It has varied between 10pm and 6am when it happens. We've tried lifting him when we go to bed but he doesn't produce anything then, just gets v.v. grumpy!
