Have to disagree as a father. The real benefit is the father and child who are now bonding. That doesn't mean the mother can't also bond, it just means it's not one sided.

I got to spend a bit more than 2 years doing math homework 1:1 with my youngest. Now, she's moving up to honors & gets 100% without any help. I miss all that time we got to hang out, do homework, watch videos of cats, etc.

The mother's are now working. So they're bonding less. I think that's what he means not that father's are taking away mother-child bonding time.
