4.25 stars - with the 1000 hours outside movement, I wasn’t sure that this book, with just 15 minutes a day being the aim, would feel very inspiring. And while it did start a bit slowly, with more general ideas, as the book went along I found myself adding many of the activities to a note on my phone to try later. So many of the things listed are so simple, anyone could do them with few to no supplies at all. A lot of them would also be great for homeschooling families. I appreciated the number of ideas that were social, seasonal, and observational - along with, of course, sports, games, and location-based. This is just a little outdated, being written in 2011, and I will say that the number of activities referencing burning calories as a boon wasn’t very inviting … but overall I’d still give this book more than four stars. I’m excited to visit these ideas with our baby, and more and more as he grows.
