Healthy bacteria are important!
Whatever means to deliver them is OK.
BTW, Mom Koala, the cuddly bear from Australia, feeds their young her own poop when they are ready to be weaned out.
Just so they can be ready for the eucalyptus leaves only diet they spend all rest of their lives on.
I just read an article about babies being born via c-section, not getting the bacteria a child would receive via a vaginal birth. It was very interesting.
