If you’re staring down the barrel of a second-child transition, I'm a Big Sister Now! is a solid addition to the 'new baby' book rotation. It doesn't try to be too clever; it just captures the sweet, simple reality of a kid figuring out how to love a new person in their house.
What sets it apart from the dozens of similar titles is the DNA of the writing—it’s based on real-world conversations between the author and her daughter. That means the tone hits a bit differently. It’s less about 'mom and dad still love you' (though that’s there) and more about the pride of being the one who knows how the world works.
