Whether a baby still needs to be covered with a blanket when wearing a sleeping bag depends on the indoor temperature, the thickness of the sleeping bag, and whether the baby's neck feels cool after erection.
1. If the sleeping bag worn by the baby has a certain thickness, and the indoor temperature can reach around 25 degrees Celsius, and the temperature of the baby's neck after erection is not cold or sweating, there is no need to cover the baby with a blanket.
2. If the sleeping bag worn by the baby has a certain thickness, and the indoor temperature is below 20 degrees Celsius, and the temperature of the baby's neck is icy, it is necessary to cover the baby with a blanket. However, if the baby's neck is warm, there is no need to cover the baby with a blanket.
3. If the sleeping bag worn by the baby has a certain thickness, and the indoor temperature is above 26 degrees Celsius, and the baby's neck is sweating after erection, not only does the baby no longer need to cover the blanket, but the sleeping bag should also consider reducing its thickness.
Generally, children are not afraid of the cold and are even more afraid of the heat, so the indoor temperature should be appropriate. The baby's clothes should be appropriately reduced or added, so that the baby's neck does not sweat or cool.
