NIght-time dryness... is a biological occurrence... and it can take until even 7 years old. Per Pediatrician's.
Night-time dryness... is a completely DIFFERENT thing, than day time pottying. So keep that in mind.
She is SO young... to even have bladder control while sleeping. AND for her to be "expected" to be fully competent at being dry at night and for getting up herself to go to the bathroom.
My daughter, was still wearing night time diapers until she was already 5 years old. She had been potty trained since 2 years old.
Do not keep waking her up at night just to pee. She will not get a good sleep that way... it will interfere in her well being.
Night time "dryness" is something that also comes with biological maturity and the myelin nerve development... its not "her" being lazy or being a problem.
This is not a problem. MANY kids... even at 7 years old... still do not have night time bladder control. Its NORMAL.
Just let her be... and use a waterproof bed-pad directly under her. I got mine from Amazon. I have 4 of them, that I use for my kids and change out and rotate if needed.
My daughter is 7 now... just last week, she had a pee accident while sleeping. NO big deal. I just change out the bed pad, put a new one under her, she changes her PJ's, and goes back to bed. We do not scold or pressure her or my son for these things. It is normal and natural.
My Husband, still had pee accidents at night too, even when he was older. Its normal.
My daughter sleeps very deeply, and one time she even dreamed that she WAS on the toilet... until she felt herself wet.
My friends kids... did not attain dryness at night until 5+ years old as well. Even my Daughter's Preschool and Kindergarten Teachers said that 3-4-5-6-7 year olds, still wet the bed and it is no big deal. It is the biological bodily maturity.
I would really stop waking her up all night just to go pee. It is just going to interfere with her sleep and needed sleep... and then the next day she will be SO tired because of that and/or fussy all day.
You don't "train" a child to stay dry all night or to go pee. It comes with age and biological mechanics and maturity. Remember, night-time dryness is a TOTALLY different process and event from just daytime going potty.
Again, a child CAN wear night-time diapers for bed and naps... no biggie. You just tell them, its only for sleeping. They do NOT get confused or regress....it is just a normal progression. Again, my daughter wore night-time diapers until she was already 5. My son, still wears diapers for nap and sleep... and he is 3.5 years old. He is not even fully day time potty trained yet. No biggie.
My son for example, knows diapers are only for sleeping or certain LONG outings where there is no toilet. They do not get "Confused."
Its fine.
My daughter... was also about 5 years old... when "she" could then recognize the pee urge while sleeping, and then in sequence, get herself up...and then go to the bathroom herself... of with my accompanying her... which is no big deal. I don't make them, especially when young, go to the bathroom by themselves at night.
As a tip: for night time, I would use night-time diapers... NOT pull-ups because pull-ups don't hold much and they leak and it is pointless. And more expensive. Huggies makes good nighttime diapers.
all the best,
