Pull My Finger

Last night when I was bathing Collin, he stuck his thumb out at me and said, "Mommy, pull my finger". I have not heard him say this before but guessed what would happen when I did pull his "finger" (thumb in this case). I did pull, he made a sound with his mouth and then laughed. I did not say anything but was dying laughing inside. I knew where he got this from. Lately, Daddy has been doing this to Collin but burping when Collin pulled his finger. Great skill you have taught him Daddy! :)
