I used to hold Hannah along one of my forearms with my hand firmly pressing on her tummy and her head in the crook of my elbow iykwim (if you need a demo, I can take a pic doing it and send ya). I also used to find that bicycling her legs while she was on her back was a winner. AND the hug a bub was fantastic - it seemed to be more comfy for her than any of the holding positions...Massaging her tummy in a circular motion in a clockwise direction (the direction of the bowel) also helped sometimes...

Poor little mite...it must be horrible for them!
