My son does the armpits, kneepits, and my personal favorite, the ear. Nothing to induce motherly pride like watching your child bang on the side of his head to make ear farts with the palm of his hand. :love
My dd does armpit, kneepit and chin against the shoulder farts. We were trying to use the webcam with mil yesterday so she could see the kids and dd1 just had to show off her farting skills. :lol
One of the ER nurses I worked with taught me (and every kid he had as a patient) how to do it. You just simply take a bendy straw and place the tip under the arm. You might have to adjust it to get it in the right place, but then you just blow. POOF! Armpit farts without all the work. :lol
For the advanced armpit blow-farter, simply hum a catchy tune while blowing. :lmao
