To be honest, I don't think anything other than a simple "thank you" is necessary. My OB was great - he looked after me throughout my pregnancy and was there when I delivered a beautiful baby girl. He was there for two, yes two, contractions - my daughter arrived with the second. And he was paid - handsomely.

On the other hand, my midwife stayed 2.5 hours after her shift change because she thought it was inappropriate to leave me when I was so close to giving birth after having spent the day supporting me. She was told in no uncertain terms by the chief nurse (don't know what the correct term is) that she would not be paid for her extra time and she should just leave it to the new shift. She stayed and was incredibly supportive - both to me and my DH, and she basically delivered my little girl and only stepped aside so the OB could "take the glory". She was definitely worthy of flowers, champagne and chocolates.
