This is a solid, sweet picture book that sneaks in genuinely useful life skills—meditation, perseverance, emotional regulation—without feeling like a lecture. The fact that it's written by Bianca Andreescu, who was a teenage tennis sensation, gives it credibility and makes it especially valuable for young girls who play sports or dream big.
It's not going to blow your mind with creativity or storytelling innovation, but it does what it sets out to do: introduce mindfulness concepts to little kids in a relatable way. The dog helps. The 5-star Amazon rating suggests parents appreciate the positive messaging.
If you've got a sporty kid or one who struggles with big feelings, this is a nice addition to the bookshelf. If your kid thinks tennis is boring, maybe skip it.
