To be honest, I doubt that they thought she would be this fertile, for this long...and didn't realize she would be pregnant pretty much every year.
It isn't that the kids that they have aren't enough for them, its just their belief to not use forms of birth control, and let God decide how many kids to give them.
I honestly have to say that they have been blessed, as all of their kids (up until Josie) were born healthy and happy. They haven't had any with a permanent disability. Even though Josie was born really premature, I still believe that she will live a happy full life.
To each their own.
Besides....can any of you say that you are debt free as an adult? Have a house, self designed, paid off in full from the get go? Have several vehicles (that include an RV and a small bus) free and clear?
