traveling a 2 month old

Iris • 🤰🏻🧒🏻👨🏻‍🦲
I will be traveling with my two month old in February outside of the country (USA) for a week and I wanted to see if anyone can give me any recommendations on what to pack in the baby bag and luggage ❤ it is my first born so I'm not sure of the rules in the airport regarding anything related to baby stuff. My baby is formula fed.
