Tickle My Armpit

Mommy:
Your most requested location on your body to be tickled is your armpit. I'll be tickling your back or your leg to calm you down before bedtime and almost always you will throw your arm in the air and say, "Tickle my armpit." We just tickle softly with fingertips or fingernails and you don't laugh when we go slow. You are quite confident in directing us in where you want to be tickled as the location moves from leg, to stomach, to feet, to back, to armpit, etc..
