You need to do what works for you.

After my DD2's birth, if I were to have another I wouldn't muck around calling my m/w out. I would think that a two and a half hour labour first time around would probably mean a short one second time, especially with the pushing being nearly half of that. I think I'll make sure my doula is close by - because DP would have a heart attack if he thought he'd have to do anything! GL!
