I have a 5yo DS who is struggling with bedwetting. The part which is leaving me confused is that he seemingly night trains, has extended periods of being completely dry then goes back to bedwetting.
For background, he potty trained during day shortly after turning 2 and initially at night at around 2.5 years. We had about 6 weeks of being dry then went back to bedwetting. Knowing it is a hormonal shift, we didn't put any pressure on, went back to nappies and left it. A few months after turning 3, he was dry at night again. This period lasted for almost 10 months so long enough to believe that he does have sufficient vasopressin overnight. We had 3 holidays abroad in this time, all of which without nappies and completely fine.
He then started bedwetting again shortly after turning 4. We did not go back to nappies at first, thinking feeling wet would kick the habit. There was lots of on/off with being wet and dry and then after being wet for 10 nights in a row, we relented for the sake of everyone's sleep (and washing) and went back to nappies.
Most recently, he was dry all summer and has gone back to bedwetting.
He is otherwise happy and well, developing fine, happy in school, eating and drinking normally. I don't restrict fluid in the evenings but equally do not encourage drinking huge amounts unless he is thirsty for a reason. Saying that, he regulates his own fluid intake with no issues. Also has no issues during the day with using the toilet.
Any ideas or advice?
