Just to say that DD is 3.7 and has never, ever woken up with a dry nappy.
A week ago she announced that she was a big girl and no longer wanted to wear pull-ups at night - completely out of the blue, never having ever been bothered about being a big girl or nappy wearer at all in the past. In fact, she seemed to love her pull ups.
So I had a panic, tried to bribe her to wait until the next day as we had no waterproof sheets etc, but she wouldn't have it. So I went to bed at 9pm , primed and ready for a night of sheet changing.
But she stayed dry - not a single accident. I was gobsmacked. After 3 nights I even did a little jig of nappy-free joy.
At exactly the same time she started to do poos in the toilet, without prompting - she just decided. Up until then she'd waited for me to come home every night and demanded a nappy for a poo (then shut herself in the wardrobe and summoned me for cleaning duty afterwards).
I thought I'd post this as both are common problems - I was waiting for her nappy to be dry in the morning before night training, but it is clear now (yes, of course everything is clear in hindsight!) that she was just weeing in the nappies because they were there. With poos I think she just decided she was ok with it, perhaps as a result of her overnight weeing triumph
