My wife received a wide variety of expert recommendations and opinions when she was pregnant with our first child. Towards the middle of the pregnancy she decided, at the doctor's advice, to reduce the depth she dove and take few risks (although the two other doctors had said not to dive at all). She enjoys seeing the interesting night creatures and the peacefulness of night diving. She would only go when the ocean conditions were glass smooth (which was often). I could always count on seeing her above me at 10 feet while several of us would be below at 30 to 40 feet. The tropical water was warm, so skin suits allowed us to not need any weight. She was also able to use the small and light 50 cubic foot tanks we had, and still have lots of air leftover. She found the events to be relaxing and enjoyable. There were also times when I just let the divemaster take the group out while she and I sat on the jetty wall and enjoyed the evening.
But before you get judgemental, here are some other facts:
*At the time she was a scuba instructor and I was a master instructor
*She was a Marathon runner and triathlete that had recently participated in the national trials
*Before and while she was pregnant, she was running 6 to 10 miles a day with one 15+ mile event on the weekend
*Several times a week she swam a mile of laps in the pool before work
*She was a US Marine Officer
*The baby was born just as healthy as can be, and is the smartest little lass a proud dad could wish for, and like mom, is also athletic. Her intelligence is not a figment of our imagination either, as tests, grades and acceleration recommendations by her teachers verify.
*The next three deliveries have led to the same results
*All of the deliveries went smoothly and naturally without any problems, pain relief, etc.
Probably the only casualty during the deliveries is my deformed hand being squeezed during the last couple of contractions. Women just don't know the strength they have, and I have got to learn when to put her hand on the side rail with mine on top, and let the rail take all of that pressure. But by the time the Doc says go ahead and push, I have waited to long and my focus is on the amazing little baby coming out, and only later do I realize that my hand hurts. And I wonder why this woman asks me to open the jars! It must be convenience, 'cause it sure seems to me that she could open any jar she wanted.
So it would appear to me that the entire issue of diving while pregnant is a complex decision by the prospective parents, and not one that others should try to decide for them. When others make blanket statements to the effect that 'this is a no brainer, and pregnant women shouldn't dive,' then that is exactly when they have exhibited, no brains. Of course, in my instructor capacity, I must give students the don't dive recommendation. Even on a personal basis, I recommend that pregnant women do not dive, although it was okay for my wife, but she is intellectually and physically far beyond most women anyway.
We did develop a new dive signal though. You waggle your hand, or secondary flashlight, and you move it downward. This means I dropped my flashlight, can you get it honey?
