Returning to the simpler time of infancy when everything was new and exciting is no problem with a pair of footie pajamas. Originally designed to keep babies snug and warm for bedtime, these pajamas also became available for toddlers, older kids and adults.

Footie pajamas—or sleepsuits, or blanket sleepers—are a common clothing item for infants. Instead of loose blankets that may pose a choking or smothering hazard, footie pajamas keep a baby warm from neck to toe with attached feet that are an extension of the legs. The pajamas have a long zipper that runs the length of the torso and ends down by the left ankle for ease of donning and removal. Toddlers got into the action when footie pajamas were made in their size, this time featuring treads on the soles of the feet to provide traction on slippery surfaces. Getting out of bed on a chilly Christmas morning, still cozy and warm in your footie pajamas, and softly padding downstairs to rip into a heap of presents is one of the most enduring remembrances of childhood.

If you really have your heart set on recapturing that long-lost warmth and safety, the wonderful world of Internet commerce can readily provide you with adult-size footie pajamas—and we promise, we won’t judge.
