I am currently arguing with someone about:
Does holding a baby upside down cause brain damage?

I was lying on the couch I held the baby on my belly, I slightly & gently lifted her holding both legs for a about 5 seconds. Now my girlfriends mother thinks the baby is going to have brain damage. I think that's absurd since a baby experiences more g-force trama at a stop sign.

Her mom switched to panic mode, you would have thought I was swinging the baby around in cirlcles by one leg like a terrible towell at a steelers game... you know. There's got to be some documentation of pros and cons on this subject.

Someone said that they did it to calm a colic baby.
The nurse did it to take measurment when she was a newborn.
Ive seen inperational pics of a mom and dad holding a baby upside down .
