We are about to travel to jaipur and it would be my 9 month old boy's first air travel. What all precaution should I take and how can I ensure that this travel is comfortable for my baby

A. If your child feels a hungry then feed the child before the flight takes off like if you are feeding basically I want the flight you can give basic food to the child if you would like to eat anything and cover the years of the child with a cotton or earplugs because air pressure is the only thing that really trouble skids a lot
