While Will has been daytime potty trained for almost a year now, we were still struggling with naps and nighttime. Finally, about 4 months ago, he stopped wetting his Pull-up at naps and just in the past week he's been willing to take a nap with just underpants on.
And just in the past couple weeks he's been keeping his nighttime Pull-up dry! We still get him up to go to the bathroom before we go to bed, but I'd be fine with that forever! I think we'll keep him in a Pull-up for a bit longer, just until I'm really convinced that we won't have lots of accidents.
But YAY for an extra $20 in my pocket each month!
