I've become sort of an accidental advocate for attachment parenting, which is a style of parenting that... basically, the way mammals parent and the way people have parented for pretty much all of human history except the last 200 years or so.
Attachment parenting is not a passive parenting style.
I have a neuroscience background - that's what my doctorate is in - and I was trained to study hormones of attachment, so I definitely feel my parenting is informed by that.
