Grandma volunteers to take on all five of her preschooler grandchildren--from three families--while their parents have a party. Lassen is delighted; Mama and Dad are often strict, but Grandma ""likes kids."" For a time, joy reigns as game follows game; but when it's time to pick up, the kids are too excited to focus on the job and the uproar continues till even Grandma shouts, ""Stop!"" and points out that she sounds just like their parents because ""I taught [them] everything they know about being grumpy. And I'm older, so I've had more practice."" So the kids shape up, pick up, and get ready for bed--with a snuggly story-time first. This slice of real life is depicted with such humor and affection that kids are sure to enjoy recognizing themselves and their elders. The soft, realistic pictures make each character an individual--Grandma is plausibly young, Dad is balding.
