The most important part of motherhood is who you have a child with.
I agree with the contentment, a pile of dad, baby and toddler on the couch, nothing comes close to that happiness.
But the space and luxury to enjoy your baby and children for me is completely tied to being with, still with, an amazing husband and dad.
I don't know if there are many counter articles from men, saying how work is work but when they get home that is their reason for working, the fulfillment they get in supporting a household because it has his babies in it.
So perhaps the number of men a similar age happy to commit and sacrifice their individual lives contributes to the lower birth rate.
But I guess women will always get the brunt of the blame, I mean not wanting to be financially reliant on a grunt is a good thing. If society needs more babies perhaps work on the males as well.
