I lurked on this thread when you first posted it.
My DS is 7 1/2yrs. He is a very heavy sleeper and we got a referral 4 months ago. We went for our first appointment and she was lovely. At the appointment we discussed how DS feels about it, (really didn't like it, thought he was stupid :( ) poo issues (he occasionaly got very bad constipation), fluid intake (not enough), urine output (very frequent, up to 18 times a day), how long he goes between wees (not very long but if we were out somewhere he could go for 3 hours without weeing), how we respond to bedwetting (no fuss).
She suggested the following:
Drinks or 150-200ml, drunk in one go, every 1 1/2 to 2 hours during the day with the last one 2 hours before bedtime.
Monitor fluid intake/output for a 24 hour period.
Keep an eye out for constipation and if it is a problem to address it.
Try to increase length of time between wees.
We set a return appointment for 3 months later.
For the first month DS was extremely annoyed about the frequency of drinks. He HATED the monitoring day.
I was very hopeful that it would help. 9 weeks in I was despairing and it had made no difference. I sat down to make some notes ready to take along to the appointment about how it hadn't helped (with the exception of no poo issues). The next morning he as dry. 3 mornings later he'd had 4 dry nights in a row. I got excited and made more notes, then he was wet for the next 3 nights. He was disappointed. I added to the notes again. He then had 5 dry nights. More notes. Another wet night. Another note.
Then he was dry again, followed by another 4. On the next night I heard movement upstairs. I went up to find him sat on the loo. I couldn't believe he was still awake but then realised that he was actually half asleep AND TAKING HIMSELF TO THE LOO. I don't think I have ever, ever been so pleased about someone going to the loo.
He is now on dry night #7 in a row.
Other things that have changed as a result.
He is noticing he is thirsty.
He has reduced toilet trips by about 1/3 and it's still getting better.
His urine output in one go has increased.
It's was a real struggle to get him to stick at it with the drink intake but it really has made a big difference. The nurse had really helped here because she had discussed all the reasons for her action plan with him directly and had asked him how he felt about it. We were able to use this to remind him why we were doing it.
Sorry, this is a bitty post but I have two hyper children telling me jokes!
