Yes, an 18-month-old can continue to wear a sleep sack if they find it comfortable and comforting. Many toddlers still enjoy the security and coziness of a sleep sack even at this age. Sleep sacks provide a safe sleep environment by reducing the risk of suffocation from loose bedding. Choose a sleep sack that is the appropriate size for your toddler's weight and height, ensuring it allows for ample leg room and freedom of movement.
Sleep sacks can be a safe option for 2 year olds if used properly. Look for sacks designed for toddlers with features like wear-resistant seams, reinforced openings, and breathable fabrics to prevent overheating. Ensure the sack arms allow for free movement and choose a TOG rating appropriate for the room temperature. Stop swaddling and use only sacks allowing arm mobility.
Toddlers can walk while wearing a properly fitted sleep sack designed for their age. Look for sacks with arm holes that go above elbows and leg openings below feet to allow full range of motion. Lightweight, breathable fabric that moves easily is key, along with a roomy width to avoid hip/leg constriction. A shortened sack length prevents tripping. Allow your toddler practice time wearing the sack awake first.
