It's a toddler's body that dictates when it's time to stay dry for a whole night. Until that happens, there's no point trying to hurry the process.
A dry night nappy is a good start
On average it takes 10 months after becoming dry in the daytime to become dry at night too. But it can take less time or considerably longer, depending on the child.
One sign that it's time to ditch the night nappeis is if your child’s nappy remains dry a couple of nights in a row. At this point, put a plastic sheet on the bed and be prepared for a few accidents. If it doesn’t work, put the nappy on again. You may need to continue like this for a while.
Waking toddlers up to pee
Many parents wake their toddlers to pee before going to bed themselves. This really isn’t necessary since the point is for children to learn to wake up when they need to go the toilet, or to get used to not peeing at night. But many families find this method useful as an extra precaution. If it works, then it’s fine.
Most children become night-trained some time around kindergarten age. If yours doesn’t, and you’re worried, consult your Well Child nurse or GP.
