Ds1 potty trained quickly and easily at 2.5 ish. I wasn't expecting night time dryness, as he was still leaking nappies several times a week at night. However, a few days into starting potty training, he woke up with a dry nappy. Fabulous! This continued for several weeks so I ditched the nappies at night too. So, dry day and night. A few early mornings as he would wake needing a wee, a few wake ups in the night needing a wee, but very quickly was sleeping through dry.
Fast forward 6 or 7 months, and he started having the occasional wet bed. Had changed nursery and was tired . Had been ill. But it got worse and worse until I started lifting him for a wee. It got to the stage where I had to do this every night, in the middle of the night, or he would wet. I never made a big deal of it. Eventually, being exhausted with this and a younger child, I started putting pull ups on at night. I figured that eventually he would start waking with dry pull ups.
He's 4 yrs 4 months. I know (because he's told me) that some times he will consciously wee in the pull up. They are wet every morning. He never gets up for a wee. He never needs a wee in the morning.
I'm thinking about stopping using the pull ups, and asking him to get up for a wee. I wonder if the sensation of seeing without the pull up will wake him, and he'll get back to it that way?
