Mum's were 8, 4, 38mins - all with waters breaking and contractions not long after. The 4th was twins and dictated epidural so not active during labour at all and was < 4 hours with twins arriving about 10 minutes apart.

Mine have been so far 6.5 active (from waters breaking, 18 from first contraction, but all prodromal labour), and second 3h45m from waters, 2hr50m from contractions.

I am a little anxious about the idea of the next given my mums history and how hard and fast my second was; and it will more than likely be a planned homebirth.
