I have two boys, ages 7 and 10. One pretty much started being dry all night at around 2 1/2. My younger one still wets the bed at 7. He wears a nighttime pullup still. My husband wet the bed until he was a preteen. From what I understand is that some children just are not developmentally ready to stay dry at night until later.
Actually, according to this article, maybe we should try to find a solution to it since my son is 7 and still does it most nights.
Here is an excerpt from an article from WebMD on it.

In the U.S., about 5 to 7 million children aged 6 years or older suffer from primary nocturnal enuresis also called nighttime bed-wetting or the involuntary loss of urine at night when they could reasonably be expected to stay dry.
Terry started wetting the bed age 4 and continued to do so until he turned 15. His family was at their wit's end and didn't know where to turn for help.
That's because myths abound when it comes to bed-wetting and they often prevent children from getting the proper help, says Alan Greene, MD, an assistant clinical professor of pediatrics at Stanford University in Stanford, Calif., and author of several books including the forthcoming From First Kicks to First Steps.
WebMD talked to leading pediatricians to debunk some of the more common myths and address parental concerns about bed-wetting. Here's what we uncovered:
There's something wrong with my 3-year-old!
"Bed-wetting is very common in younger kids, in fact, it is so common that it is even considered normal before age 5," Greene says. "Nighttime dryness is the last part of toilet learning that kids achieve," he adds. At ages 6 and below, bed-wetting only needs to be addressed if the child is feeling really bad about himself as a result, he says.
"As adults, when the bladder gets full, it sends a signal to the brain to wake up or you start dreaming about water or going to bathroom, and then you wake up, but for kids the signal isn't quite strong enough to get them awake," Greene says.
That's why "it is normal for kids to wet the bed," agrees Charles I. Shubin, director of the children's health center at Mercy FamilyCare in Baltimore, Md. "By age 6, one out of six or seven will do it."
He adds that bed-wetting is "a developmental issue and therefore the treatment is time, so for kids age 6 or under, they will most likely grow out of it."
Good luck! And I wouldn't really worry to much about it as it most likely will resolve in time with or without intervention.
