I am glad your parents can help by preventing brother and sister from teasing you. (I was the target of a lot of teasing when I was in your position). Have you checked medical reasons: Urinary infection Yeast infection These can cause bladder spasms, resulting in sudden wetting. Have you tried a bed alarm? This thing can build the habit of waking up. It is very useful in most cases, helped me a lot. Bedwetting is also often caused by emotional troubles. Any number of sources of stress can be the root, even if it seems trivial. A counselor to talk with can sometimes help work it out.
