Is noumal for my 12 year to wet the bed after eattting weater melon?

Yes - I think it's normal for any child to wet the bed. Sometimes when a child goes through a growth spurt the bladder needs to play catch up. Maybe just to make sure its nothing else - ask your child if something happened that's upsetting them. May they just need to talk. If it continues please call your doctor. AND as for the other people who answered your question with a smart *** remark about your spelling and other wise crackers - don't pay any attention to what they say - I think their the ones who need the counseling or maybe they just need to grow up and get a LIFE. Hey smart es - If you have children - I FEEL BAD for them - but I'm guessing you don't because if you did - you would know how it hurt when something is wrong with your child and you don't know why. All this person wanted was answers - NOT bull ****.
