"The day you deliver, outside will be foggy. Your baby will arrive in the early morning. After a labor lasting approximately 19 hours, your child, a boy, will be born. Your baby will weigh about 13 pounds, 5 ounces, and will be 20-1/2 inches long. This child will have dark blue eyes and some black hair."
Somehow, I'm not putting much faith in this prediction. My longest labor so far was 6 hours... and that is stretching it, including pre-labor. My babies have all been around 8 pounds. I mean, this one could be different, but I don't think I'm going to jump from 8 pound babies to a 13 pounder.
Although, all my babies have had dark blue eyes and dark hair at birth, so I guess that part could be right.
