We are in disagreement over what the overwhelmingly common experience of men and women in parenting is. I'll just grant you for fun that I am too ideologically biased to notice that my wife and I parent in basically the exact same manner. I'll also just grant, again for fun, that you have the inside track on how my 15 month old son experiences us as parents and that he sees no difference.

Still, imagine we interview 500 parenting couples and their kids and ask them simple questions: 

"Do you guys feel like there are really no significant differences in the way you parent as moms and dads?"

and for the kids

"Kids, do you feel like mommy and daddy parent you in basically the exact same way or are there some differences?"

Which direction you think answers will tilt?

The breastfeeding thing was an example by the way but more examples. Don't you think parenting after the onset of puberty is just a LITTLE different between moms and dads and how they relate to sons and daughters?
