Parents of young kids, is PJ Library worth it?

Hello!

I just heard about PJ Library and it sounds perfect for my kid (she’s six).

My wife and I are constantly looking for books to read to her before bedtime and hearing that there’s a literacy program dedicated entirely to Jewish families sounds perfect to us.

I was wondering if any parents in this forum have used the service. Was it worth it? Were the books of quality (like, are they educational? Do they teach good lessons? Are they fun for kids)?
