More are more likely than girls to wet the bed.
Sometimes they are afraid of the dark,even if there is a nightlight, and sometimes they just sleep to hard and do not wake up. I would reccomend buying some mattress protectors pads. I used them while potty training my kids. They go between the sheet and mattress. They keep the mattress dry. They are not the same as the fitted mattress pads. I hope this is helpful. Some boys wet the bed until 12 years old (my nephew, and husband).
