Just tap and say "Mama"

Sam has recently taken to running up to me and gently pushing/batting me with both of his hands. It's not very hard, but I don't want it to turn into hitting. I had a theory that maybe he was just doing it when he wanted my attention so I decided to teach him to tap me on the shoulder or leg with one finger to get my attention. When he came up to me as I was finishing dinner and pushed my leg with both hands, I took the opportunity to stop him and say that if he wanted my attention, he should say "Mama" and use one finger to tap me. I demonstrated this by saying "Mama" and tapping his shoulder gently with one finger. I went through this several times and it appeared he was starting to get it. He decided to repeat it back to me to show me he understood it. So he said "Mama" and gently with one finger tapped his own shoulder. Of course I meant for him to tap me like I was tapping him, but being the literal toddler he is, he thought he just needed to tap his own shoulder and say "Mama" to get my attention. Needless to say, Dave and I had a good laugh over that. :)
