12yo Is It Normal For A 12yo Girl To Still Be Wetting The Bed At Night?

Is it normal for a 12yo girl to still be wetting the bed at night? - 12yo

My partner has a 12yo daughter who wets the bed regularly. Use the pull-ups every night, but sometimes it is not, and bedding must be changed.
My concern is that it is almost in school and, therefore, soon the camp school, friends want to sleep, etc. "houses, but it will also interfere with it.
The extra weight could be a cause of bedwetting?
Does anyone have experience with the treatment of enuresis alarms and, if so, how they have proved to be useful to you?
Thanks
