This kid can squeal!

I thought we were out of the squealing stage. Since birth, Ryland has always had a high pitched squeal. When he was little, it sounded like we had a bird. Now, when he gets impatient at meal times or wants to get up on the couch, he squeals/screams. I don't know how you get a child to stop that, but if anyone has suggestions, let me know. It's like it comes and goes. I'm ready for it to go!
