I've learned that people with PWS are individuals. Yes, they share common traits and features, but they are also different from each other in varying degrees. Some don't have any PW features while others do. Some children's behavior problems begin earlier than others. Some parents don't have to lock their refrigerator and cabinets while others do.
Some kids are skinny while others have a major problem with their weight.
I guess what I'm trying to say is don't worry about all the things you may read or hear. Just take care and love your son and do the best by him that you possibly can. For you see, my son Cory's behavior problems didn't start until his late teens. Even at that, we have found medicine that helps in this respect. We don't have to lock our refrigator or cabinets.
