V.E.
My son, Matthew is 25 months old, and I can literally "feel", and see what you are saying, here. My son did nearly the exact same things, but has all but ceased to perform them. I ignored him (and I mean, I wouldn't even glance in his direction) if he didn't RESPECTFULLY communicate with me. No screaming MAMA, no hitting, slapping, foot stomping or anything else. He learned quickly that if he calmed down and said, Momma, mom or something similar in a nice voice, that I would focus 100% of my attention to him. This worked for me VERY well. Good luck and god bless, V.
