My son he is 4 years old ever. 12 month he is having cold.

Hello Roshini, Feed him warm food and soups. If possible give him steam. What I used to do when had to give stem to my baby, I used to hold him in my arms and myself also sit with him and playfully make him sit near the steamer. You don not have to directly put his nose infant of the steamer but should have the baby in your lap and let the steamer be a little away to avoid it from falling. Do you mean he feels like vomiting while you are travelling? In that case you can give him a medicine to treat nausea. http://www.webmd.com/cold-and-flu/cough-home-remedies-babies-toddlers
