It's normal for boys to wet the bed until age 17.
I myself wet the bed until I was 17 and had wet the bed from potty training and until a little after my 17th birthday.
I saw the doctor about the bed wetting when I was 7 and the doctor said that it was just normal and that I would eventually outgrow it.
I wore diapers for the bed wetting until I finally stopped wetting the bed.
My parents had me wear those old thick pampers diapers until I was around 10 years old.
Then we switched to the larger diapers after I couldn't fit in the toddler sized diapers anymore.
Then I wore adult sized taped on diapers until I stopped wetting the bed a little after 17.
If I remember correctly the bed wetting stopped in myself around a week or two after my 17th birthday and to me that was the best birthday present I could get, even if it happened later.
Bed wetting is normal and some kids may stop wetting the bed sooner than others and some kids may never wet the bed after potty training.
But although it's embarrassing, many kids and teens and even some adults wet the bed.
