Traveling with a baby

Karla
I try to search this topic but I don't see a lot of comments. But I need all the information that I can get because I am traveling with my baby for the first time. He is 8 months old. Any tips.
How much formula I can take?
How many bottles?
Strollers?
Anything that can help me. 
I am traveling a lone with him so I am kind off nervous.
