How do you know when to night time potty train?

[shelfontheelf]

3.5 year old twins (girls, if that makes any difference) have been trained since July but are still in nappies at night. How do you know when it's time to ditch the nappies?

There nappies are always wet in the morning but I think this is from weeing first thing when they wake up - not overnight, but how do you know?

Thanks

Ds just requested not to wear a nappy one night. He was fine.

Why not give it a go tonight?

Ds's nappy was also sometimes wet and must have been the morning wee.

How good are they at holding wees?

Yep we just tried it! To help, you can layer sheets with waterproof mats so if they do wee you only have to clean them and take old off, not faff about trying to put new sheets on. Think we had 3 the first night!!

My daughters the same age and I tried her a few month back and she wet the bed alot, so I put her back in pullups on the nite.

Sometimes shes dry in the morning and goes to her potty and has one long wee.
Im just guna wait until shes dry more often and then try again without.
Im in no rush.
