I do think it is somewhat crazy to just expect your parents to drop everything to help you after giving birth. I guess I don't understand the whole "I had a baby, I need help" thing. With my kids, my mom was still working full time (and many mom's of new mom's are) and couldn't take time off from her job to stay with me, nor would I have ever expected her to. When my daughter had her baby, I not only worked full time, BUT still had special needs young ones at home. I will say that even if I could have stayed, she wouldn't have wanted me to - her and her husband were completely capable of caring for a newborn between the two of them.
Have your husband take paternity leave and stay home with you for the first week and let your parents come when they are ready.
