A 2.5 TOG sleep sack is designed for cooler weather or colder room temperatures. It provides a higher level of insulation compared to the lighter TOG sleep sacks.
Since a 2.5 TOG sleep sack is designed for cooler temperatures, dress your baby in layers underneath. Start with a short-sleeve onesie or T-shirt in a breathable material like cotton. Add a second layer like footed pajamas or a sleep and play. The two light layers will trap warmth while still allowing airflow. You can also do a long sleeve onesie or pajamas with socks. Avoid heavy fabrics that could overheat.
A 2.5 TOG sleep sack offers warmth equivalent to two or three lightweight blankets. However, sleep sacks are safer than blankets as they reduce suffocation and overheating risks. Blankets vary in thickness and materials, impacting the comparison. Opt for a sleep sack to ensure a safe and consistent sleeping environment for your baby, following recommended sleep guidelines.
