transfered is also not a good way to say it, it would be like the baby has the ability to produce milk inside its body with the energy that is coming off the mothers skin. Something like that
Honestly it's just a dumb analogy all the way down.
The way an infant acquires nutrition before birth, is entirely different to the way it does so after birth, and neither is remotely similar to "charging".
My wife would absolutely disagree with this. She could "feed" the baby anywhere before, but now she has to sit every 2 hours every day. And that's 2 hours from the start of the last feed; more like an hour break in between.
I find it even better when you think about the oxygen instead of the food, since babies become able to breathe on their own entirely without parental intervention.
