Traveling with a 2 month old

P

So my little girl is due August 11th and in November my cousin will be getting married in Flordia. It’s about a two hour flight from where I live and a 16 hour car ride. I plan on flying if I do go. I am so nervous with her only being probably around 2 months old it’s been giving me anxiety I am suppose to be staying for a week in a condo. I just wanted to hear any success stories and tips on traveling with a baby that young.
