If you have 2 or more kids how quickly does the second one really come? I’m terrified i will give birth in the car on the way to the hospital because i don’t know when to go. I don’t want to go to early and get sent back home. I went after about 3 hours of contractions with my first and i was already 6cm dilated but had been 3 cm for a month before that. I had my daughter at 41 weeks and was in labor for 12 hours from the first contraction to having her in my arms. How many weeks did you make it with your second compared to your first and how long were you in labor?
