Hmm, my DH *and* I are both having stressful times like that right now. I am more often the one staying up until 1 or 2 am with work and then getting back up at 5:30 or 6:30 with our 2yo DD, or to work some more. I'm trying to do baby prep on the weekends, but I have to work on the weekends, too. DH just finished a hugely stressful test about 2 weeks ago that caused him to be out of the house working or studying about 16 hours a day for over a month straight, leaving me largely as a "single" 8 month pregnant mom of a 2yo with a 60+ hour a week job. So, his worst time is now over, but he's been rather sick and run down since then, and still feels pressure to work 12+ hours a day. We have gotten very little baby prep done, and we are both exhausted.
It's stressful, and it kinda sucks, but it's life. We have a doula for the birth, too, but nobody postpartum. Our family will want to come up and visit after the baby is born, but honestly I expect them to be more of an added responsibility than real help, so we're going to try to make them wait to come until at least a few days after the birth. Love and adrenaline will pull us through, and it will be fine.
