Can the placenta be given to others at will? Will it affect the baby?

I won't. As long as the umbilical cord is cut after the baby is born, it will break away from the "mother-child (female) relationship" from that moment on, and the placenta is like an "old house" abandoned by the baby and will never come back! You say yourself, will what the baby abandons still affect the baby's life? Honey, don't listen to others! Wish the baby health and happiness!
