Sleep sacks can provide sufficient warmth for winter when the proper TOG rating is chosen. Look for sacks with higher TOG ratings of 2.5 or above to provide insulation during colder weather. Pair with footed pajamas or add a bodysuit layer underneath. For extremely cold temps, consider a sleep sack liner for extra warmth. Be sure to monitor your baby's temperature and watch for signs of overheating.
For a winter sleeping bag, a TOG rating of around 2.5 or higher is recommended. The TOG rating measures the thermal insulation of the fabric, and a higher TOG indicates a warmer sleep sack. A TOG of 2.5 is suitable for most winter conditions, but you can adjust the clothing layers under the sleep sack based on the room temperature to keep your baby comfortable and safe.
No, sleep sacks do not hinder a baby's development. In fact, sleep sacks can be beneficial for a baby's safety and comfort during sleep. Sleep sacks are designed to provide a secure and cozy sleeping environment while reducing the risk of suffocation associated with loose blankets.
