Being dry at night is hormonal and not a skill to be learnt.
I think nights take a lot longer as you can't train for it. Mines also dry in the day but wears one at night still and it's always full
Wait it’s a hormone thing. When she’s been consistently dry for like a week then remove nappy (and get waterproof mattress cover). It’s not volitional so not anything you can do except take nappy off first thing etc and encourage her to toilet then. My first was ready at 3.5 having potty trained (with difficulty) at 3. But my niece who potty trained beautifully at 2 still not quite there at 4.
It’s definitely based on the child itself rather than training! My little boy was out of nappies day and night at 2y2months but my friends little boy still isn’t out of nappies in the day! I don’t think you can compare on this one x
With my girl, she did it on her own. You have to wait for her body to learn to hold the wee.
From my understanding, being dry through the night takes much longer to master and sometimes nearer to 5 years old rather than now.
