Lee T Gettler

So Darby Saxby just published a wonderful book called Dad Brain, talks about how the dad's brain changes.

And Lee Gettler, who's in one of the episodes, talks about how men's hormones change, in particular how testosterone drops and oxytocin and prolactin rise when we're involved in infant care.

And that's evidence of father nature.

That's evidence that our bodies are wired to do this, but we have to do it through the work of taking care of an infant.
