Momma is a word you only say when your MAD!

My child's first word was dadda and that was fine with me, I was just happy when I heard his precious little voice say anything. However, it's been months now since he has started saying little words and I'm very distraught about Brody saying Momma. The only time my precious little wild monkey says Momma is when he is mad at me. It never fails when I take something from his little paws that he shouldn't be touching in the first place he screams Momma. Hey I was happy to get that, but I want him to say Momma through the grocery store like he does his Dadda! Oh well I guess one day he will say it when he is happy!
