Here is something that no one ever told me... sippy cups and bottles WILL leak because of the pressure, so pop the cap off the baba or whatever just till you get up in the air. Stickers were a great distraction, a simple notepad and two crayons will go miles. I was also 6 months pregnant and travelling with a 18 month old...I can so relate! Dont over pack, take the minimum you can get away with...a simple backpack will suit you best. You can check your stroller at the gate, so dont check it with your luggage. When you go thru security, you will have to break down your stroller to send it thru the x ray, ask them to help you. Make sure you bring a few ziploc baggies, different sizes in case you do need to do a diaper change, or for dirty napkins, whatever. When you check in, ask if there are any empty seats (tho not too many anymore) so you will have some squirming room just in case. If there is a favorite bedtime pal, that is a must (plus you will need for nap/ sleep at your destination). Mostly, dont be afraid to ask for help if you need it. And dont be surprised if people give you the eye roll as they sit next to you. Do you remember the name of the people the last time you took a flight and they're kid screamed? Nope, and if your baby doesnt handle it well, so what... its a few hours out of someones life, and they'll get over it. More than likely, your baby will be an angel...and youll give back advice to someone else who needs it. Good luck have fun and let us know how it went!
