Isn't that great?
Some couples have different needs, abilities, capacities inbetween them; I think if all parties are happy it would do much better for the children, rather than conforming to a standard 'men working, women caring' ideal, which while not exactly -bad- the way this is also not -bad-, can be restricting.
And I sincerely don't believe this change in ideal reflects in any way a lesser degree of love / compassion each parent has for their child.
