Little Nathan loves his days with his mother and father. He loves their attention, he loves their snuggles and he loves playing with them ... when they are able to play. When he learns that his parents are going to have another baby, he is initially excited and imagines that he will have a playmate. But then he notices that things are changing in the house — changes that he doesn't like. Luckily Maggie, the Tulip Tree Elf, offers a perspective on the coming changes that helps him not only feel more welcoming to the baby — but honored to become something very very special: a big brother.
