The "boneless baby" is the heaviest time of a female's menstrual cycle. I.e...the gelatinus uterine lining that sluffs out of the vagina while taking a hot shower.
Holy crap husband! Our boneless baby was so dense, I didnt know whether to breast feed it or diaper it, so I just kicked it down the drain.

P.S. Cant wait to see you next month my boneless baby!
