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.
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.
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.
