Almost any book on raising young children (say birth to 5) would be written with the assumption that diapers, feeding, play arrangements, and what we might call "very early childhood education" were the responsibility of a mother. Many early children's books would feature mothers as the ones taking care of young children too, and that grated on me a bit.

To be fair, there's a flip side to this which is almost as bad. By the time my child ended up at a (co-op) nursery school, I of course got huge karma from all the other stay-at-home mothers there for doing precisely what they did. That wasn't comfortable either, but at least it was an ego massage.

A couple of decades later ... it all seems like water under the bridge now compared to the deeper gender politics that we still face, and I am only glad that it made me pay attention to what I had previously assumed was a trivial thing.
