One-month-old babies are relatively fragile because their organs and systems are not fully developed. Parents are advised to adjust the indoor temperature and humidity in a timely manner to keep them relatively constant, with appropriate adjustments made according to seasonal differences as well as differences between the north and the south. It is generally recommended that the temperature be kept at 22°C-26°C and the humidity at 50%-60%. At the same time, parents also need to pay attention to the frequent opening of windows and ventilation to keep the indoor air fresh. Also pay attention to the temperature change of the baby’s skin, you can touch the skin temperature of the back of the baby’s neck. If the skin of the back of the baby’s neck is warm and not sweaty, it proves that the indoor temperature is appropriate; if the skin of the back of the baby’s neck is moist and sweaty, it proves that the indoor temperature is slightly high, in which case, the indoor temperature can be appropriately lowered or the baby’s clothes can be reduced; if the skin of the back of the baby’s neck is low and the hands and feet are cold, it means that the indoor temperature is low, so parents are advised to appropriately raise the indoor temperature or increase the baby’s Clothes. Higher ambient temperature or infants wearing more clothes may cause infants to be irritable, cry a lot, sleep poorly, wake up easily, eat significantly less, and have red rashes on their backs. Since infants have a low resistance and are prone to fire, it is beneficial to their growth and development to be in a more comfortable environment.
