Anyone know how to get an almost 2 year old to stop screaming? He does a high pitch scream because he knows we don't like it and he thinks it's funny. It's getting really annoying. We have tried time outs, spanking (doesn't phase him), I will squeeze his leg (he cracked up because I guess he is ticklish), ignore him, pinch his foot (thinks it's ticklish)...he just laughs at anything we do and does it more. So if anyone has ideas I would appreciate them!
