Pinky and Rex and the New Baby - James Howe

When her family adopts a new baby, Rex tries hard to be a perfect big sister. But Rex spends so much time with the baby that she has no time left for her best friend, Pinky. Until Pinky finds a unique way to show his pal that she can enjoy the best of both worlds, even with a new baby in the family. Full color. Rex's parents are adopting a baby, and Rex doesn't like the idea at all. Suppose her parents are so busy with the new baby they forget about her? So she comes up with a plan. If she can be the perfect big sister, her parents will have to pay attention to her. The trouble is, being the perfect big sister is a lot of work, and it doesn't leave time for much else -- like her best friend, Pinky.
