My first was 6 hours and my second was 3. They told me with my third as soon as i feel a contraction to call them! My 3rd they honestly don't know how long i was in labour for! I went in to get some sleeping tablets as i couldnt sleep and they did an internal and i was about 8 and a half centimeters dilated! they broke my waters and about 10 minutes later i had a baby in my arms! 4th baby i was induced and had her in about an hour from breaking of waters to baby in my arms!
