Birthing Plan

I am really wanting to keep my baby's umbilical cord attached until it dries out & save my placenta. Because it is soo much better for the baby & I dnt want to give my placenta away because they make soo much money off of it & You get nun in return for that precious placenta of yours. Also eating the placenta gives you back your nutrients that you lost, help with postpartum depression & many more... Have any of you mommys thought about this too ??
