By 12 months, babies are pulling up, cruising, and potentially walking. Footless pajama designs allow for more mobility and reduce tripping hazards at this active stage. Enclosed feet could also be frustrating and get in the way as 1 year olds gain independence practicing new skills. Separate sleep sacks are commonly used at this age as well. With sleep sacks or blankets for warmth, footless pajamas keep the torso and legs covered without restricting newly mobile babies. Allowing toe freedom reduces frustration while keeping wiggly 12 month olds safely contained during sleep without dangerous loose bedding.
