I myself had two kinds of births. The first, at home, in the twilight / dark my contractions developed well and the delivery progressed quickly. The second, despite strong contractions and complete access yet to the hospital. After arriving my contractions did not return, this through the bright light, and especially the massive distractions, unknown people and loud sounds, etc., resulting in one complication / medical intervention after the other. I wonder whether women with AD(H)D are more susceptible to contractions ceasing when distracted for example by bright light during childbirth, than women without AD(H)D.
