My son is 6 1/2 and still wets the bed. It's just now getting better. We've taken him off night time pull ups and started taking him for a pee around 11:30 pm. Now the bed wetting is only occasional, and he's starting to wake on his own to go pee at night. It took a long time, but he's a heavy sleeper! I was the same way, I wet the bed until I was nine. I was also a heavy sleeper, and remember having the "toilet dream". If he does wet the bed we treat it like it's a total non issue.
