It's hit or miss. But some parameters help narrow down the pool: not an only child, has lived on her own outside her parents' home, pictures in their profile not focused on loving mom and dad. If their personal statement is full of gushing of how warm and loving their mom and dad are, I'd pass. During interviews, ask about any adversities they've encountered and how they overcame them.
My most independent ap came from a hard background. Both her parents died when she was relatively young and she was raised by a relative. She was completely self sufficient and independent.
Having said all that, we do have family dinner together most nights. With 3 kids at such a young age, you have to be very frank during the interview process about how busy your household is and set realistic expectations. Most aps find 3 kids a tough job.
