How does the concept of a wet nurse work? If continuously given a newborn while nursing a 2YO, does she continue to produce milk until there isn’t another baby?

Question

I also know that a nursing woman’s body can adapt the milk to provide for what the baby needs, but how does that work when the newborn needs a ton of stuff and the 2 year old needs something specific?

(I’ve been reading a lot of historical fiction lately)

Answer 1

Yes. As long as there is a baby that keeps nursing then the woman will continue to produce milk. As for the milk changing for the child’s needs it likely wouldn’t be as successful in the scenario you describe but that’s part of the deal.
