I laugh because I accidentally picked the day of my daughter’s birth. I figured the sonograms were wrong, went from the EDD on the later sonograms, and counted back because I usually have my babies early. My kids were having fun guessing the days, and I guessed the 13th of September (due the 10th by 1st sonogram, and the 18th by later ones). My 9 year old daugher wrote it on a calendar she kept. Well, she pulled it out after I brought the baby home, and lo and behold, I had picked the date exactly.
