We are often asked, “Can I use a blanket with a baby sleeping bag?” No you should not use a baby sleeping bag with a blanket. Baby sleeping bags are designed to be used alone and without any additional cover, so your baby does not overheat. We advise for extra warmth that you can layer your baby up with their pyjamas or sleepsuit and a baby vest or onesie. For a nursery temperature of 10-20 degrees we do recommend using a 2.5 tog baby sleeping (this would be a Babasac with the layers in), for a nursery temperature of 10-15 degrees with pyjamas or sleepsuit,15-20 degrees long sleeved bodysuit, sleepsuit or lightweight pyjamas) 19-20 degrees 1.0 tog (a Babasac baby sleeping bag with its inner layers removed). For use in warmer weather or nursery temperature 21-23 degrees (with a short sleeve bodysuit or vest) We recommend that you use a room thermometer to check the temperature. The ideal nursery temperature is 18°.
Baby sleeping bags are designed with armholes to allow air to circulate, so that your baby does not overheat. This is why baby sleep bags do not have arms on them.
Young babies hands are often cold during the night, this does not necessarily mean that they are cold and they need more layers. Babies circulation is not yet working properly and this means their hands and feet can feel cold. It is unlikely that this will wake them up or cause them any distress. It can be dangerous for babies to overheat, so please be careful before adding extra clothing.
