Children's ✦ Penny’s Take
Weekly Reader Children's Book Club Presents Sloth's Birthday Party
Diane Redfield Massie · 1976
72/100
👍 Worth It
Sloth's Birthday Party is a small, warm picture book that quietly handles social anxiety and belonging in exactly the way young children need — gently, through a relatable animal character. Massie's own illustrations carry the charm, and decades of nostalgic affection from readers who found it through their school book clubs speaks to its staying power. The catch is that it is only available used now, so discovery takes effort.
