Families with new babies and older siblings will see themselves reflected in this ever-so-sweet story of sibling rivalry as a young elephant gets frustrated with all the attention his baby sister is receiving. Toby is no longer a little elephant. He's a big boy now, much bigger than baby sister Iris. He can do exciting things all by himself. He can pour his own milk, read his own bedtime stories (sort of), and even reach the snacks high on the shelf that he's been told are "just for mamas." But sometimes it feels that Toby has to do everything by himself because Mama is too busy with Iris. And some things are really hard even for a big boy. Toby ends up with spaghetti on his nose, rain boots that don't match, and toilet paper everywhere! He is mad. Luckily, Mama is there to remind Toby of the perks of being a toddler--and that no matter how big he gets, he'll always be her baby.
