No, they are a Christian family. And their social skills, from what I’ve been able to discern, are more advanced than average kids.

Large families, I’ve concluded, are great for kids.
By the time #3 rolls around, the parents are pretty good at it (if they follow biblical training principles).

Another aspect of families is that they teach everyone in them about their relationship with the Heavenly Father. Parents and children alike learn from this little micro-model of the father-child relationship.
