The first 1/3 of the book makes a pretty good case for the importance of little rituals. They build trust, relationship, etc. They serve as inside jokes or shortcuts for quickly touching back to those trusting, cooperating, loving moments. (My take, not exactly what the book says.) And lots of stuff on the importance of having well centered, trusting, loved kids.
The remaining 2/3 are little rhyming games to do on fingers or bodies during quiet times (e.g. as you're getting ready to put shoes on or off, sitting in a waiting room, etc.) or slightly more active activities, too. They're aimed at the 2-4 year old set, ideally, but a few were instant hits with my 6 and 8 year old. Complaint: Many involve taking a classic nursery rhyme (e.g. There was an old lady who lived in a shoe) and re-wording it heavily to make it somewhat sappier and more positive. We all know how dark those rhymes can be! But they're not very intuitive. However, if they're treated as examples and starting points for people to make up their own little rhymes and games, it's helpful. I am more intentional about touching the kids, making eye contact, and choosing my words to build connection.
