What I loved: The colors and ideas here are very cute. The story is relatively simple, and the colors are really bright. Children can relate to playing on the playground and approaching new potential friends, who may be different than they are. There are also some interesting new ways to classify the alphabet presented herein, which may spark some creativity.
What left me wanting more: A big thing that is missing is the resolution of the fighting (they eventually just all swing and are happy), but they were pretty rude to each other in the process with excluding based on differences. Reading between the lines, you can see that the four make something special together (LOVE), but this is never stated and their arguing not resolved- just ultimately ignored.
They are also all referred to as the first/second/third/fourth letter, which is not always easy to say aloud and also difficult to remember which one is which. The sequential ordering could be helpful in terms of a learning point, but the order is not so obvious, so it can be confusing at times.
Final verdict: Overall, this is a cute and simple picture book that presents new ways to look at the alphabet and can spark some discussions about welcoming others who may seem different than you.
