In the first baby, the time from the contraction to the delivery is something like two days, with random contractions every two hours or something, it's (more) difficult to sleep. When the contractions are frequent enough you go to the hospital and wait a few more hour. Ask the doctor for the details.
It's not like in the novies! Nothing is like in the movies!
The first two days after the delivery are terrible. The baby has tummy ache and cries and cries and cries and cries. You can try to fix it with some tummy massages. Ask the nurses in the hospital for help, they have a lot of practices, it's like magic. Usually after two days it get's better, hopefully.
As another comment said, babies have a lot of variation. Don't get too worried if they don't follow exactly the calendar. I've never seen a calendar with sigmas. Ask the doctor.
Doctors also have a lot of variation. Try to get one that is good and that fits yours preference. Bonus points if s/he understand what you want when you ask for a calendar with sigmas.
Once the kid enters kindergarten, s/he will get all the silly contagious illness. Expect to have her/him at home like 50% of the days during the fist 2 or 3 months.
