Newborn babies are particularly vulnerable to extremes of temperature. Their temperature mechanisms are not yet fully developed, so strict attention needs to be paid to their warmth and clothing. Keep the temperature of their room pleasant, but not hot (around 18-20°C). For winter outings cover your baby’s head with a woollen hat, hands with mittens and feet with warm socks or booties. When indoors remove this extra clothing to prevent overheating. In summer, do not overdress your baby, and choose loose fitting, light clothes. Cotton underclothes are the most comfortable for all weather, and should be changed every day.
