I don't like doing it.
Heaven knows I make every effort to use a firm voice instead when disciplining. But sometimes, I really end up shouting. It never escalates into anything really bad, but I know I sound mean sometimes. I know I sound really angry sometimes. I know others get scared that I might start shouting more, or hitting my child (my temper is legendary!). It's a good thing a mother's heart can never be immune to her baby's cries or smiles (like most kids, my son thinks it's still play when I get upset). Weird, am trying to discipline him but he's also teaching me a lot about self-discipline.
And always, he is a saving grace. Just like my husband.
