B.P.
You have gotten a lot of good advise so I will just tell you that my son also had this problem about 5% of the time. He is a sound sleeper and couldn't wake up until it was too late. He is 8 now and has been dry almost a year. We never gave him a hard time and he has no issues from it. All kids develop differently and no kid would do this out of laziness. Good Luck
