You know what, OP? I think you resent the changes that having 3 children in 3 years have brought to your life, especially when compared to your DH's life.
I think you should go back to full time work as a civil servant with your new "transferable skills", put the kids in daycare or swap roles with your DH. Because with this level of bitterness, defensiveness, vitriol, lashing out, you're not doing anyone any favours (least of all yourself). You're certainly not doing your kids any favours. Just wait till they're older.
You do what works for you and leave everyone else alone. If a woman wants to do night-feeds "because her husband works", leave her be. It's nothing to do with you. It's just as likely as not that she doesn't need you to 'protect' her.
I'm ranting now, but your posts are just so fucking patronizing. Billions - BILLIONS - of women all over the world, throughout time, have done more than you: multiple children, working in the fields, widowed, divorced, unforeseen sickness, ill parents to look after as well, livings to earn, just fuck - LIFE. They just get on with it, sometimes with loving partners who do their share, sometimes without, because LIFE. And you're going on about sharing night wakings? Like you're the oracle of women's rights? Your very first post was aimed at the women who 'let' their children's fathers sleep, not even at the fathers who sleep. Can't you see yourself?
Jeez. Grow up.
