Newborns are somewhat uncomfortable with the change of external temperature difference. The suitable indoor temperature should be kept at 25℃ ~ 28℃, and the temperature should be reduced appropriately in midsummer, but it should be kept warm in winter. But when ventilating, pay attention to having a heater next to it. But indoor light should not be too dark or too bright. Some parents think that newborns are less sensitive to light and are afraid of irritating their eyes. They often like to hang heavy curtains. In fact, this is not appropriate. Babies should learn to adapt to natural indoor light and avoid direct sunlight. Clothes and diapers Newborn underwear (including diapers) should be mainly soft and easy to absorb water, and it is best not to use chemical fiber or printing and dyeing fabrics; Clothes should be light in color, which is easy to find dirt and prevent dyes from irritating newborn skin; Clothes should be as loose as possible, which does not hinder physical activities and is convenient to put on and take off; Due to the large amount of heat dissipation in the newborn's head, a small hat should be worn when the climate is cold or the room temperature is low, and it should be soft and comfortable.
