Dunno if this thread is totally done or what, but wanted to chime in. My DH is wonderful and we've been through some trying times in the last year and a half (open heart surgery for him a few months after we got married), and we're generally having a great time being parents. He interacts with the boy, potties him, kisses the baby before me when he gets home, cooks dinner, and brings home the veggie bacon so I can stay home. He even potties him in the middle of the night.
So why am I resentful so much of the time? I used to work as a nanny, so it's not like I didn't know what I was in for as a SAHM. I don't feel cooped up, I just feel like I do everything! And I know that I don't! But you know, I get one half hour to myself every day, while I'm in the shower. One half hour, out of 24. And who do you think I'm thinking about while I'm in the shower? DH and the boy, of course, wondering if DH is resenting me for leaving him in bed with a baby who's not going back to sleep, thus making him get out of bed. And when he gets up at night to do potty duties, I feel like he resents me. Why am I imagining resentment on his part? It's like I don't want to ask him to do anything more than he already does because he might get angry, which I know in my heart he won't.
Has mamahood made me totally insecure? I mean, just because I don't get paid doesn't mean I'm not working all day too, right? So it's fair for us to split childcare duties when we're both home, yeah? Maybe it's hard for me because I did used to get paid for this kind of work, so I feel like I'm asking him to do work I'm supposed to be doing.
I think the main difference between mamas and papas is that even when we're not with our DC, we carry an emotional burden of caring for them, which is hard work. I very much doubt that fathers spend a lot of their workday worrying whether the baby is eating enough, or getting enough attention, or whatever it is that we mamas think about all day. Plus, we're constantly making milk, and I often forget to take into account how much energy that takes.
Sorry this is so long. DS is asleep, so I have the time to write this while I should be doing things like...ummm...I can't remember. Oh yeah, brushing my teeth.
