Before formula, what did moms do if they did not have enough milk on their own or a wet nurse? Could they pull milk from various other animals? I am inquiring about moms anywhere in the world during history.
/u/amifufu has previously answered Before we had things like Formula, how did infants whose mother died in childbirth get the necessary nutrients that are in breastmilk?
/u/mimicofmodes has previously answered In older days let's say before infant formula was invented how did lower class/poor families tend to/feed newborns in circumstances where the birth mother died during labor and couldn't afford/ get a wet nurse.
/u/Superplaner has previously answered Before specially made baby food. How did the people of your era feed their babies?
Your question is very broad so more answers could well be written.
