I come from a 11 kids family also.
Even if she passes on before the kid reaches adulthood, at least there are all the children and grandchildren who could step in and help as necessary.
You know what I mean.
Only 7 kids in my family and we were all by immaculate conception. My mother never had sex and if she did, it was only because she had to and she didn't like it!!!
I have an Aunt who had 11 children. Life was always interesting at their house.
