Ok, so our boys will be 3 and almost 2 when we fly in September. Obviously, we had to purchase a ticket for the soon to be 3 year old(this Friday). I'm trying to figure out if we'll need a carseat for him in the seat that was purchased. He's pretty close to 40 pounds and tall for his age. Most people think he's 4 if not 5. We're flying with Southwest. I'd call them but honestly I'm anti-social enough that I'd rather ask on the web than talk to some stranger. Also, does anyone who flies with SW know what the procedure is as far as strollers? We're assuming that we'll be able to take them on the plane but not exactly in the carry on way. They're little foldable strollers that are quite compact but about 40-48 inches in length. This will be our first time flying with littles so it should be interesting. We've read that suckers are a good way to keep them calm when the air pressure starts messing with their eardrums. Plus, we've got mini-tablets for them to stay entertainedduring the flight. Memphis to Orlando is less than 2 hours so we should be good. Fingers crossed. Any tips or ideas from you guys? Thanks!
