Every night, about 5 or 10 minutes after I've tucked the little guy in and said goodnight, I hear him running to the bathroom. Initially, it was "I need to pee" and if he was still awake 20 mins or so later, he'd often return to the bathroom again for another pee. He admitted most of the time it was only a dribble that came out. This has been going on for a little over a month now, except for the past week it's changed to "I need to poop", which mostly results in him sitting on the toilet trying to force out a poop by over-straining. Most of the time, he doesn't succeed and I manage to convince him it's not ready yet, other times, he manages to squeeze out a tiny poop, but I'm concerned he's going to hurt himself by straining so much.
I've tried explaining to him that he shouldn't have to strain like that, and reminding him when he goes to poop how it normally feels, as he poops just fine before at other times of day which rules out any constipation issues.
Tonight would be a good example, he pooped normally around 7pm just before his bath, he got ready for bed, went for a pee and I tucked him in. It wasn't long before he was back in the toilet again, needing a poop apparently, despite already going for a poop less than an hour earlier. He was unsuccessful, which had him visit the toilet again around half an hour later, again unsuccessful, except for a pee.
Myself and my wife are of the opinion this is all in his head, but that's not easy to know for sure as we have no way of knowing when he needs to poop. We can only guess.
He's never wet the bed, or had any other toilet accidents since he was a toddler where he didn't make it to the toilet in time, but that was years ago. So we can't think why he suddenly has this idea in his head that he needs to go so often at night. During the day, he doesn't go often at all, in-fact he often comes home from school and tells us he hadn't peed all day, which to me seems an awfully long time to hold your pee. We've told him to pee at break and at lunch, or at least one or the other, but not to go a full school day without peeing.
Anyone else experienced this or have any tips on how to handle it? I don't want to force him off the toilet in-case he really needs to go, at the same time I don't want to leave him straining to the point he might hurt himself.
Thanks in advance for your advice.
