Books like Smiles to Go

I always think it's funny when books say "My first....", "My first ABC book", "My first book of rhymes", "my first book of Holiday's",etc. I mean how many "first's" are there before "first" isn't a big deal.and yet, I think this book could marketed as "My first book of existential crisis" The main character realized protons die and questions the nature of everything while being with others for not recognizing the gravity of things."I don't necessarily like the idea of introducing the idea of self doubt to kids and I probably would have given this book 3 stars but I had to move it to 5 because my son recommended, actually *insisted*, I read it. The thing is, that being a divorced mom of a 10 year old boy can bring about a myriad of insecurities I'd not even considered. It's compounded by the fact that his dad shows up occasionally and sweeps him off to surf in SanDiego for weeks at a time or takes him backpacking around Mt. Hood, while I - - - ? um, read to him. That's some pretty stiff competition for me to compete with.So the fact that he cares what I think about his book, that he wants to share the story with me and asked constantly "what page are you on?", and we shared bits we liked here and there means it's a 5 "sentimentally-starred" book for me.
