Traveling alone with 7 month old!

3 hour plane ride alone with my 7 month old son next week. Any tips or suggestions are welcome! I’m nervous lol.

Luckily we are flying JetBlue and they are usually super nice and accommodating. I also have TSA precheck. Just kinda worried my son is gonna be THAT kid that screams and cries the whole plane ride 🤦🏼‍♀️
