Our son is 7 and has never been dry in the day. Night times he is responding well to a buzzer from local continence clinic. He has plenty to drink and has had a scan to check if all is OK. No problems to report there. He does lots of tiny wees. As many as 20 a day, and we are constantly changing wet trousers when he doesn't reach the loo in time. Our nurse suggests next step as Oxybutynin. Would really value your experiences. Have you tried it with success? side effects? or chosen to try to make better capacity through building up holding on times? Thanks.
