R.D.
Definately a phase. I have two boys and one went through it at that age and the other one is following suit. What I did when he hit or swatted at me I would tell him we do not hit and put him in time out for one minute (I have a specific place I use for time out...1 minute for 1 yr old). I then go to him when time is up and explain in his words that it is not nice to hit people and then I give him a hug and tell him I love him. I do this everytime to show that what he did was wrong, I forgive him and still love him.
