Assistance became interference. Cords can actually break on their own with mild tension. For Mother Nature, that’s how it works.
Babies were being born before doctors and nurses were around to clamp anything. Yes, if something is squirting red, clamp now. But foals, calves, lambs, babies all have umbilical cords. That’s why we are all mammals.
Thanks for the reply. The miracle of birth is truly amazing.
