Ok so this is going to be a bit of a weird first post, I really apologize. Lately, DS has been having constant nighttime erections. And I don’t mean just a little bit firmer and plumper like before he has to pee, which I’ve seen before. These are huge, his penis points right up his belly and sticks out of the diaper when I come to change him while he’s asleep, and its usually so stiff that I can even point it down into the diaper. It’s really making for some tough diaper changes in the middle of the night and the morning. Is this normal for 18 months?
