I did a pregnancy photo shoot (about 3 years ago) of this mama who, when I dared her to join the volleyball game, didn't hesitate for a second! She precipitously delivered five days later.
(I wasn't her midwife, but when her labor raced towards birth, she knew I was close by and called me. My former apprentice and I flew to her home, where she was alone in the bathtub. Her daughter was born into mama's hands about 5 minutes after we got there. Her midwife arrived not long after and her husband and son awhile after that. It was a lovely birth.)
(Can you tell I'm scanning pics?)
