With our first, I was convinced I wanted the very private mommy/daddy/baby experience. My husband took two weeks off and we insisted that nobody come help. I really regret it. I had a three-day labor, and DH and I were both exhausted. I couldn't really stand for several days afterward. At least I had the rush of hormones, but DH was really a wreck (and needs more sleep than I do anyway--so starting out fatherhood after two nights of no sleep was really tough for him). If only we'd let one of our eager, willing relatives come and cook for us and we could sleep--it would have been much better.
With baby 2, we took all the help we could get. Now that we're expecting #3, I'm just shamelessly sending out calendars to relatives and scheduling them all in for multiple visits this summer! But then, I'm also much better now at articulating what I need and setting boundaries. We have good relationships with our parents and will have enough space in our new house to have some privacy when we need it, which will help--the last two births were in small apartments.
