Yippee! It's a snow day. Lucille is jealous when her big brother and sister head outside to play in their sleek snow pants and jackets while she's stuck inside putting on her snowsuit. Literally stuck--her zipper won't zip and she can't get her snowsuit over her boots. Worst of all, "Snowsuits are for babies and I'm not a baby!" she yells. With a little help from Mommy, Lucille finally runs outside to join the snowy fun, and that's when she discovers that perhaps snowsuits are indeed best for making the most of a snow day.
