I took my 2 1/2 year old in my -4 all the time. I would bring his chair that he watched tv in and strap him into that. Sat him up high enough to see out, which is the biggest issue in my opinion. They get bored really fast if you don't. We would keep the flights to less than 30 minutes. He fell asleep a lot, but boy we had a great time flying around to different airports, grabbing a soda and just hanging out. Great memories. He can't wait for me to finish my -8, but he's still way more into being a cowboy than a pilot. JUST DINT FORGET THE BATHROOM BREAK BEFORE YOU GO!!
