Just Me and My Little Brother by Mercer Mayer
This cute book is part of the Little Critter series that I personally grew up loving. It’s a good book for toddlers or older kids who are about to become older siblings. As you read through the book, try and have them imagine what they will do with their new little brother or sister, just like Little Critter does. I like that it talks a lot about the older sibling teaching things to the younger, and the two of them sticking together against bullies and snowball wars. It’s a good lesson for any siblings, really.
With short but interesting sentences and well-drawn, vivid pictures of all different animal children, it’s visually appealing to all ages, too. Check out the rest of series for other great reads.
