I have delivered twin babies. A boy and girl. Both of them are catching cold very often. Once in 2 weeks they are falling sick. Mostly they have cold in the chest and they cough. We use nebulizer at home. It is effective but once again they catch cold. We are also giving them monticope daily as preventive medicine. Can we do something else to prevent. Could this be due to sweat. Any home remedies we could try or could you advice on how to manage.
