Finally, a solution to replace loose blankets in the crib, keeping baby safe, warm and cozy all night long. Just layer this over your baby's snug-fitting cotton sleepwear and let the snoozing – or strolling – begin. The double-ended zipper makes diaper changes a breeze while super-soft, breathable cotton helps keep things cool. (The enclosed design keeps little legs and feet away from crib bars, too.) All in all, as ingenious as it is adorable. Features fun-loving dots against a white background.
