I've heard of people not cutting the umbilical cord until days after the baby's birth, why did they do that?

That sounds like a bit of misinformation you were given. What they meant was not cutting the cord for a short while (maybe 5 minutes or so) until it stops pulsing (or the blood stops flowing through it). This is because it can take a short while for the baby to completely switch over from receiving oxygen through mom to using his/her own lungs. Cutting the cord immediately (which is routine in hospitals) makes the transition longer and harder on the baby. The blood in the cord is also a strong healing agent and it's beneficial for the baby to take that with him/her.

I've never heard of that. It doesn't make sense to me. But I do know of some grown men that need to cut the umbilical cord with their mothers.

Because they want to be under one accord.

I guess they want to do it old school...I would assume that early man (or shoudl I say woman) had two options when a child was born..carry the child around until the umbellical cord dried and fell apart (much like bats do) or chewed through it. I think it's kind of a copout to go a few days then have it cut, I say if you are gonna do it old school do it all the way...

I've heard of people letting the cut cord drop off and it does after a few days, but who in the hell would leave the baby and the cord attached to the mother? What???
