We are all a bit naive as first time moms! I know I was, at least. Just try to go with the flow, trust your instincts, and (of course) sleep as much as possible. With a good support system you'll be fine! It's also important to communicate with DH as often as possible (daily) about expectations, how you're feeling, what you need, etc. It may seem like there's no time to do that, but make it a priority! DH and I were in the honeymoon phase, and then BAM it was like we just started unloading all of our unmet expectations onto each other. It's hard to try to understand the other person's POV (hubby working, but I thought it was great he got to get out of the house and talk to adults, he thought I had it relatively easy being at home, etc.) So try to keep up with that. We still have to try hard to regularly communicate- it's so easy to put it off when there's such a wonderful little person running around. Also, it's a transition for everyone, so be GRACIOUS to one another. You'll do great :)
I've been impatient as can be throughout my pregnancy to get to November already and meet my baby. I definitely think that being a first time mom is the reason I'm going into parenthood without many worries, lol. I don't know the half of how my life will change, even though people obviously warn me all the time of the sleep deprivation and responsibility I'll be facing. I'm looking forward to the feedings, diapering, snuggling, milestones, all of it --- well, except of course sleep deprivation. I don't think anyone looks forward to that. LOL
But I do have one disclaimer to my naïveté. I am extremely nervous and panicky about finances and figuring out how to balance work, homemaking, and motherhood. I've always had a really hard time multitasking... It gets so overwhelming to not be able to switch gears as easily as the next person. I don't know if it's just a focus issue or anxiety in general, but I'm looking into getting help for some of it so I can learn to manage things better. I'm just really scared of not being able to exclusively breastfeed and cloth diaper my little girl because of my difficulties balancing work and personal life. My mom is gifting me a really good breast pump at my baby shower, so I'll have the supplies to do it. But being able to switch gears at work regularly to pump, and then coming home from work to switch to mommyhood when I switch off with my husband so he can go to sleep (we work opposite shifts) doesn't even sound possible. I think I'll break down right away. I'll have to consider getting a different job that provides me with a schedule I can manage, if things don't work out with me at this current job...
On the flipside, though, I'm really hoping that having the love and joy of a child in my life will put me in a different mindset where maybe things will actually get better where my nerves are concerned. I am an extremely nurturing person and I haven't had much to nurture besides my husband and cats for the past several years. I am happiest when I'm nurturing, and I think that being able to dote on my little girl soon will be so great, I probably won't have as much time to worry about other stuff!
