Mine was even bigger... But I'm big, too.
I sat cross legged, boppy on top and had FREE arms. One went around him Along his back, and the other held a book. (2 hr nursing and burping sessions. Hour to nurse, 30-60 to burp). Without a book I'd have died of boredom or fallen asleep.
My legs and the angle of them/ the pillow kep him in, the arm was just extra.
LOL... My FOOT would often fall asleep, but when I put him on my shoulder for marathon burping I'd stretch out my legs. I'd sometimes just cross leg ONE leg up and rock with the other, then switch when he switched sides. But that was when he was older/ even bigger.
