Haha, I surely didn't have it nearly as bad as Cynthia Jeub. Super Christians, yes, extremist homeschoolers, no. There was no abuse, but damn did I feel neglected and ignored as a child.
My parents are 3 of 12, and 8 of 11. Both wanted a huge family too, but had to stop at 6 kids biologically. So there was also adoption and 10+ years of foster care to make sure our household was never less than 9 or 10 at a time.
As the second oldest... Expert babysitter by 10 years old. Left the church at 14. Decidedly Childfree at 16. Moved out at 18.
