DS (4.9) and DD (3.6) still have pull ups for bed.
Occasionally they will wake up dry but it's not reliable enough to not use the pull ups.
Everyone else's children of the same age appear to be dry at night and I have no idea how to do it.
They take a small flask of water to bed, they go to the toilet before getting into bed.
I guess taking the water away is the first step?
