My 3y4m DD has been toilet trained and using the loo by day fine for a while now. At night she wears a "sleeping nappy" which is a pair of size 6 Pampers nappy pants.
Over the last week, I have gone to her in the morning and the pull up is sodden and hanging off her with the weight of wee, PJ's and bed soaked too (but she is sleeping through it all).
So I'm guessing this hormone that is supposed to kick in and keep them dry at night and/or wake them up for a wee hasn't kicked in yet.
She has a few sips of water with her tea and a very small cup of milk before bed. She usually does a decent wee on the toilet before bedtime too. I can't imagine this is creating this volume of wee.
Any ideas? In the first instance is there a stronger brand of pull up or should we go cold turkey and try her with no pull up one night? Go and wake her and take her for a wee? She is super grouchy if you wake her early for anything, so don't fancy that, but if it helps, needs must.
