DS is 5, and has literally had 2 nights ever where his pull-ups have been dry. The rest of the time they are soaking wet in the morning, and he has even started leaking through them at night recently.
We have gone through phases of trying without them - he is really keen - but despite having no drinks after 5, going to the loo at bedtime, and us waking him up when we go to beds (have tried spells of doing this, and also not) it doesn't work. He's often soaking even by the time we wake him to go. Or if he isn't, and manages to go then, he still goes again later during the night and wets the bed.
He has no access to a drink at night.
At what point do we start to worry? He is a very heavy sleeper, and never even wakes up when he wets the bed - we only know about it once he wakes up in the morning - he would happily asleep soaking wet all night!
Is there even anything we can do? Don't want to take him to a doctor and make him feel likes there's an 'issue' with him, as he's not massively aware of it being a problem at the minute - we try to treat it lightly and gloss over it - though he clearly doesn't really want to wear them, and also doesn't like waking up wet.
He has no issues during the day, and toilet-trained relatively easily at 2.5/3.
Andyadvice/reassurance from anyone out there? Thanks :)
