The best method for taking your baby's temperature is by placing a thermometer into your baby's armpit (an auxiliary temperature). The temperature should read 36.1 to 36.5 degrees C, this is normal.
When your baby is born it enters an environment that is significantly colder than that he/she has been in. So precautions must be taken to keep your baby warm. His/her head is 20% of the body surface and is wet on birth and therefore must be dried. When an adult is cold they compensate by shivering which raises their body temperature. However a baby does not have this mechanism to keep warm. Instead babies are born with a special kind of fat called brown adipose tissue, which the baby metabolises to produce warmth.
However, perhaps due to these reasons babies are often kept too warm, which can lead to dehydration. When going out on a cold winter's day the head, hands and feet must be covered.
