The fact that the ????? lasts longer by a baby girl than by a baby boy shows that there is more ??????? by the birth of a girl than by a boy!! “
Funny that you mention that – I actually was thinking of it, but chose not to add it to my previous post. There is another reason for the tumah lasting twice as long by the girl, and that is because every female born, carries in her AT BIRTH her future potential for creating additional life. So the tumah is both for the mother and the female baby, hence the kedusha is likewise double.
