DS is just 4. Has been dry during the day since he was about 2 1/2 with the odd accident. For past 6 months or so we have been using night time pull ups at night as it seemed he had outgrown nappies plus I thought when he does get bigger and wakes up in the night needing to wee he would be able to do this as he can pull a pull up down himself. These worked really well until the last few weeks when he has woken up in the middle of the night wet most nights. Initially I thought he'd outgrown the Huggies night time ones so switched to Drynites 4-7 but they kept leaked too (he seemed to push them down in his sleep) so I switched back. He isn't a great drinker during the day so we're working on trying to get him to drink more earlier in the day rather than at the end of the day. Does anyone have any other suggestions as to what to do? We're all knackered, his behaviour is worsening as he's tired and I'm struggling to keep up with all the washing this is generating. I don't think he's ready to go without a pull up at night (when it doesn't leak its very rarely dry in the morning).
