Look, look, another woman here! :) Anyway, I was considering joking that as an expecting geek mom, that if men's brains get rewired, then perhaps there's a chance that I'll become more maternal. I worry about it.
The rest of your commentary makes sense to me. So far, I haven't been getting much advice that is critical of our plans, except from one person: my very traditional mother, who is probably secretly horrified that my husband is going to stay at home. She's already claimed that my longterm breastfeeding plans will never work out (no, not _that_ longterm, I just mean that I'm not doing formula if I don't have to), that trying to use cloth diapers is silly and my plans to downsize to reduce debt so that we can afford for my husband to not work mean I'll "never live in a house that big again".
Okay, I've gotten it off my chest now.
