T.,
I have flown a lot recently with my 5 month old, and she is exactly the same (doesnt' like to sit, gets fussy in the evening, etc). I would recommend doing the following:
- When you get to the airport, ask if you can bring the bucket (the baby seat) on the plane with you. Even if you have not purchased a seat, many airlines will allow you to do this if there are open seats.
- If they say no, bring it with you and ask again at the counter. Gate check the bucket at the gate and pick it up if you cannot bring it on board. Try not to check it if possible, as it's nice to have when you get off.
- Bring a sling with you. I have a moby, and it was wonderful for putting my daughter in when I didn't have the bucket with me. She could eat and then just fall asleep, and I had both hands free to read, get stuff out of the overhead bins, etc.
- When they call for preboarding, get on the plane, put your stuff where your seat is, then head to the back in the galley. If your son is like my daughter, he will really enjoy looking at all of the people coming on the plane, and the flight attendants usually love playing with the babies. Sit down as late as possible.
- He will cry, and it's ok. Just remember that the people that may get upset are just jealous because they aren't with their children :) If he sleeps in the car, he will probably fall asleep pretty quickly on the flight.
- If he is sleeping on the descent or ascent.. DON'T WAKE HIM TO FEED HIM! He will just get fussy and his ears will bother him. If he is asleep, he should be fine. However, if he wakes up then give him a breast/thumb/pacifier/bottle to help with his ears.
- If you are bottle feeding, you can bring pre-mixed formula with you, but you cannot bring powdered formula wiht bottled water to mix. You will have to buy water inside the terminal, and it's EXPENSIVE. You may want to think about buying some of the pre-mixed stuff (like enfamil) so that you don't have to worry about mixing lots of bottles, etc.
