5 hours is very fast - did they use pitocin (Oxytocin)? Without pitocin, and without breaking the bag of waters, labor takes much longer (so Dr's hate it), but it hurts much less.
My wife had two pregnancies: one was 52 hours (with five hours of pushing!). The second was about 2 hours total.
Neither involved pitocin.
Baby was 9 lbs, 9 oz (4.3 kg).
