I noticed that everytime I yawn aloud with my mouth wide open. Ryan will instantly paused, stopped at whatever that he is doing or attracted to and will watch me intently. He will have this puzzled look in his face without blinking his eyes and watches me until I finished my yawn. He will wait for me to look at him and he will instantly break into one of his sweetest smiles of all time!
I have not failed so far to get a smile out of him by repeating this action. It is just so cool!
This does not always happen to my wife no matter how many times she yawns. We just can't explain when and how it got started. I guess I must have a very funny contorted facial expression that excites and tickles him to no end. Well, at least he has found a clown at home to entertain him.
So, do you have any particular facial expression or action that tickles your baby and gets rewarded with his / her sweetest smile?
