Mommy Abuse :-(

My precious little angel has started to form a habit of a not so precious or angelic act. He beats me up!! Ok well not really..but my CJ has been showing signs of aggression towards me more frequently. He will hit, bite, pull and kick. He saves it all for me too. I don't get it. Why is he taking out his frustrations on me? I know he doesn't really want to harm me but I prefer his hugs and kisses much more. I have read online that when children do this you should either just walk away or turn them away from you. I have tried...this seems to frustrate CJ even more. I am sure this is a phase and I will be looking into more techniques I can you to get my little boy to vent his frustrations in another way.
