Sleeping bags and covers?

If the weather is warm, the baby is already warm enough to wear a sleeping bag and does not need to be covered with an extra quilt. However, if the ambient temperature is low, the baby is not particularly warm after wearing a sleeping bag and needs to be covered with a quilt, so it needs to be determined according to the ambient temperature and the baby's own heat generation. Baby needs to wear sleeping bags as loose as possible, to prevent too tight, in case of overheating affecting the baby's sleep quality. Also need to pay attention to irregular judgment of cold and warm, timely release or add clothes.
