Apparently some boho hippy chick in the US wants to have her baby in the water surrounded by dolphins, which she thinks are going to help her along. Get a grip lady. What makes you think the dolphins want you giving birth in their water messing up the pH and making the place look untidy? What makes you think they want to see your sprog being popped? They have troubles of their own you know: sonar, propellars, hippy dippy freaks wanting to commune with nature. Leave them alone and go book a hospital bed like everyone else.
Or hang this mobile in the corner of your birth chamber and imagine. Less trouble for the dolphins I can assure you.
