Little babies do find the time they had cold and cough quite a difficult part of their lives. But the horrors are extended to their caretakers and to their parents, who share the torment of the baby's discomfort in the form of sleepless nights.
The best natural remedy to cold and cough for any baby less than six months old is the mother's breast milk. The baby can build up an immunity against the infection helped by the antibodies present in the mother's breast milk. It is the best way to provide all the hydration to the baby too.
Battling an infection as a common-cold is most likely to need a lot of energy on the baby's part. It is most likely to be exhausted after the battle. Remember that babies grow up and can treat disorders while they sleep. Let the baby sleep for a long time in a place it is going to be comfortable in. It can be in a baby-cot or even in a corner of your bed-room. Make sure it is not disturbed in any manner while it is sleeping, and it is sure to lose all signs of the infection when it finds itself awake.
Some nasal saline drops prepared at home are going to give your baby a lot of comfort from the trauma it undergoes while it goes through the infection. You can easily prepare some at home by dissolving a pinch of salt in eight teaspoons of warm filtered water. Let the solution cool down and use it as needed.
