Weighing in to agree. Or maybe just to pile on.
I'm a new father and I already can not count the number of times my wife and I have already been asked the cutesy "so how many diapers has he changed?" question.
The automatic assumption that I'm just going to phone it in -- not to mention the assumption that my wife would put up with me, were I that type of person -- has already strained more than a few relationships.
Never mind that my wife had a difficult labor, unexpected surgery and was stuck in a hospital bed, leaving me to handle everything other than breastfeeding, for the first four days and it never even occurred to either of us to call a grandmother in as a ringer.
We just always planned on each doing as much as we could and so my stepping up when she couldn't was the most obvious and natural thing in the world. At least, to us.
Seemingly half of everyone we know expected I'd hold my daughter just long enough to hand her to my mother and then head back to work.
And as to the people who see my wife out and about and ask in shock/concern whether it's a good idea/whether I can really handle looking after our infant daughter by myself while she so much as runs a few errands ... I have never actually been so angry as to see red before.
