How to nightime potty train

[qazxc]

DD has just turned 5 and isn't dry at night. Nappies are always wet in the morning.
She has started to become self conscious about wearing nappies ( crying that she'll always have to wear them, asking me not to tell anyone she wears them at night, ...).
I thought that as time went on the nappies would go dry and we could start trying to go without, but it doesn't seem to be happening.
Am I doing it wrong? Should I be actively training her? If so how? Is is it time to go to the doctor about this? Is this not normal?
There are no issues during the day.

No, you cannot actively train her to be dry during the night.
I've heard about some parents (on Youtube) who ditched the nappy completely once starting potty training, arguing that it will just confuse the child otherwise and if it can learn to be without nappy during the day, it can do so during the night, but that's complete bullshit. Because that means, that the child will have to get up during the night to pee, which is not very beneficial to it's sleep.

In contrary to daytime, staying dry during nighttime is not about using the potts/toilet, but about not needing to pee. There is a hormone that regulates urine production while sleeping. It's different for every child when these hormone kicks in, but once it does, the child will stay dry during the night.

It's not unusual for a 5 year old to still pee during the night, but there is no harm in going to the doctor to have it checked. There is the occasional child which doesn't produce this specific hormone - or not until rather late - and it can be given to them as a substitute instead.

Thanks it's what I thought originally but with family asking why isn't she dry at night yet, you start to doubt yourself.
DD goes through phases of being upset about it, but I don't want to remove the nappies too soon as it would just be setting her up for failure.
