My son is really into screaming these days. He wakes up and starts yelling. Bored in the shopping cart? Better yell. It isn't an angry yell-- it is just a loud high pitched squeal / scream. It ummm, makes going out in public interesting. We've tried ignoring the behavior to see if it will stop and we've tried discouraging it, but he seems to find it really fun!

Anyone else have this issue? He is 14 months -- will he grow out of it soon (please).
