It's important to keep babies clean and dry by changing their nappies regularly. Be sure and clean them carefully after each bowel movement. Your baby's face, genitals, and hands should be sponge-bathed daily. Then you only have to give them a full bath every two or three days. New babies still have their umbilical cord. Until the cord falls off, only give them sponge baths. You should clean the umbilical cord very gently with a little surgical spirits on a cotton wool pad. Don't pull on the umbilical cord - it must fall off naturally.
Never leave your baby alone in the tub. Babies can drown in just two inches of water. Before you bath the baby make sure you have washcloths, shampoo and so on nearby so that you don't need to leave the baby unattended in the bath or basin.
Water that is too hot can burn your baby. If you have a water heater in your house set it to 49°C . Be sure to test the temperature of the water with your elbow before you put the baby in. It should feel just lukewarm - 38°C. A lot of people bath their babies in a baby bathtub. You can put that in the sink, regular bathtub, or on a changing table.
