Ds is 5, has been reliably day dry since before 3. He suffers from night terrors and we know sleeps very deeply. Every single morning without fail his night time nappy is sopping wet. We've tried lifting him and restricting drinks in the hour before bedtime, it has no effect at all. When he was 4.5 he started to say he wanted to try without his nappy so we let him. He woke up sopping wet in the morning but hadn't woken at night when he did it. After the second night of this he said he wanted to go back into nappies.
Over the weekend just gone we initiated it again and asked if he'd like to try again, he did, so we let him. The same thing has happened and he doesn't want to try again tonight. There is absolutely no pressure from us, but as he is showing no obvious signs of readiness we've wanted to see if he needed additional encouragement. I don't care about pressure from family members and have no problem explaining that his body just doesn't seem capable yet. But ds has started to ask about sleepovers and I'd hate for this to end up making him anxious. We've sort of resolved to let him stay in his nappies for now and periodically suggest trying again, but if it doesn't happen naturally with a little encouragement we'll seek help at the point it begins to worry him - at the moment he's not unduly anxious about it and we don't want to make an issue of it. He's otherwise healthy, happy, confident etc.
AIBU taking this approach? Does anyone have any advice or experience to share please? I know it's considered relatively normal up until 5, but not sure when it becomes a 'problem' (other than the sleepover issue of course).
