Well dd1 was about 8. Dd2 is 6-1/2 and still uses pullups.
Medical studies have proven it's a hormonal balance thing, and some kids just don't have the hormone until they're older.
What do we do? Provide the pullups, and let it be a non-issue. Both girls wore(wear) them, and they just quietly go about their business and toss them in the garbage each morning.
It's just not an big deal to me, and I'd rather buy a few pullups than waste half the night washing bedding etc...![]()
Our ped. told us the same thing, that it is a hormone that helps with staying dry at night. You are the first person I've ever come across that has heard that too.


He likes to lay around in bed in the morning. So...when school ends in May I'm going to take away the pull ups and see if that helps him. My friend recommended a sheet cover so I don't have to wash everything everyday if this ends up being the problem.
...My oldest stopped at 4.5yrs, I was shocked, since I was a bed wetter till 9.
