Another Sibling? NO WAY!!!

So in my mom's culture or something her mother told her.... when your youngest one starts doing this manuever it means that they are looking under their legs for another sibling and that another sibling will be coming. WHAT? Not sure if it's a "Tall Tale" but Logan actually started doing this around the time I became pregnant with Kira. So Kira's started doing this now so I am guessing it's just the age because there is NO WAY possible I'd be pregnant again!! LOL! Silly Kids!!!
