Arms up sleep sacks, also known as "swaddle sacks" or "wearable blankets with sleeves," can be safe if used correctly and are appropriate for your baby's age and development. These sleep sacks allow babies to have their arms up in a natural, self-soothing position, which can help comfort some babies and reduce the startle reflex.
Use a sleep sack instead of loose blankets for safe warmth. Choose an appropriate TOG rating for the room temperature. In cooler weather, add lightweight footed pajamas underneath. Opt for breathable fabrics like cotton to prevent overheating. Set the temperature of the room around 68-72°F. Place a warm bodysuit or pajamas on for sleep, not daywear. Swaddle newborns or use transitional sacks. Try a sleep sack liner for extra warmth. Make sure baby is dry before bed. Add a wearable blanket over the sack if baby seems chilled but avoid overdressing.
Yes, zip swaddles can be safe when used properly. They are designed to provide a secure and snug swaddling experience for infants, which can promote better sleep and reduce the startle reflex. However, it's crucial to follow the manufacturer's guidelines and ensure the swaddle fits properly, not being too tight around the baby's chest or hips to allow healthy hip development.
