Bear, the diminutive stuffed-animal hero who adjusted to having a baby-sitter in Bear and Mrs. Duck, welcomes a cuddly cub sibling into the family in the latest Winthrop/Brewster collaboration. When Nora, Bear's owner, goes off to Grandma's house to get a baby sister for Bear, he imagines he'll be a helpful big brother. But he never expected that "baby" Roly-Poly would be larger than himself, or that she would not look at all like him (she is a panda), or that she would cry so much.
