A 3 yr old’s first flight in a Sonex
I took up my daughter, Selina, for the first time this past week on Friday. We bought a booster seat, but we’ll have to return it as it’s too big length wise and gets in the way of the control stick. We ended up boosting her up with a folded blanket.
She had a blast, didn’t cry one bit. She did have to hold her headset in place for the entire flight, so that’s a little problem we’ll have to solve, but otherwise, it should all work out just fine.
She is a bit too short to be able to see outside unless I put the plane in a turn, so we may have to try and boost her up a bit more. It was fun to finally take her flying. I look forward to hundreds of more hours with my girls.

I have a booster seat that might work for you. A piece of foam and some “redneck” tape will fix the headset. Had the same problems with my girl at 2 yrs. of age. Have fun!
