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 diaper 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 diapers is if your child’s diaper 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 GP
