My son is 5. He is still in night time diapers for bedtime and naps.
My daughter was that way too.
Normal.
And normal per Pediatricians.
All I did, was explain... to my kids that their body... is not ready yet to be dry at night. Hence, the night time diapers. They understood. All you have to do is explain to the child. You need to explain to them.
AND get, a few waterproof bed pads. To put DIRECTLY under him when he sleeps.
I have 4 that I got from Amazon.
Easy.
The sheets do not get soiled that way.
I just rotate them as needed.
ALL of my daughter's Teachers, from Preschool to Kindergarten to 1st grade, said that this is NORMAL. It is biological development of the body/brain/myelin sheath nerve development. And kids these ages, wet the bed or have accidents. It is childhood. And they wear night time diapers.
Pull ups are useless for night time, because it does not hold much and it leaks. USE Night Time Diapers. I use Huggies. And I also, change my son 1 time a night... when the diaper is over loaded. He does not wake.
This is all about the physiological biological development... of the child's internal organs and brain connections and nerve development.
Not the age of the child.
Night time dryness, is not something that is physiologically attained, until even 7 years old, And this is normal and per our Pediatrician.
Some kids, are later than that.
Don't wake him just to pee. Then he will get lack of sleep/sleep deprivation and be fussy the next day.
My daughter, even at 7 years old, had night time accidents.
No biggie.
I just changed out the bed pad, she changed pj's and went back to bed.
