As part of my Post-K Summer Reading Boot Camp: https://sarahleastories.com/2019/06/08/post-k-summer-reading-boot-camp-2019/
Black Bird, Yellow Sun, is like a poor-man’s Eric Carle. This is down there with Chicka Chicka Boom Boom, which is one of the worst kids books ever–in words and pictures. I try to keep in mind that I can’t expect (nor should I expect) a striking narrative for an early board book. However, the words are large and contain repetitions of blends (e.g. bl for black, sn for snake, etc)–great for early readers. That said, the illustrations are quite bad–the rocks don’t even look like rocks but gray blobs. The bird isn’t a character but rather, just some random bird who coexists with a worm (also random). If you don’t like this (and even if you do), I highly recommend Little Owl’s Day and Little Owl’s Night (https://www.goodreads.com/book/show/20307476-little-owl-s-day?from_search=true). The Owl books are the charming, narrative versions of the stark bullet points of Black Bird.
BBYS is one of those books you’d give to your child to play with and look at but not add to your library where they might actually last for the grandchildren.
Suggested activity: Use this book as a scavenger hunt guide (i.e. have your child look for pink flowers, gray rocks, et cetera).
