Awesome outer space books for babies, toddlers, Pre-K, and beyond! Space is pretty fascinating and as your toddlers start to learn about the gigantic world around them, they might just take a shine to all things space. I know ours certainly did! Book suggestions for babies and younger toddlers (0-4) as well as some that are geared toward older toddlers, preschool, and even school-age kids (4-8 in some cases). Early learning about the planets, solar system, stars, astronauts, and the galaxy!
