We're about to fly cross-country with a toilet-training child who is growing wary/weary of diapers, which anyway seem to make her confused sometimes, not always sure if she's OK to go in her pants or not.
So after some discussion with the kid, we're opting for Pull-ups [or the Pampers equivalent, actually, since Pull-ups are Huggies, and the girls' Pull-ups have Disney Princesses all over them and are thus not allowed anywhere near either end of my child.]
But now the diaper bag is "the airplane bag," just so you know. And rather than run around strip malls in the desert, looking for a toilet seat we haven't tested, probably won't like, and won't keep anyway, I'm breaking out the 409 and packing our stark Starck ring for the trip. Which turns out to be a pretty fine piece of equipment after all, whatever its designer pretensions. The plastic is thicker and softer, while most other toilet seats I looked at were thin, hard, and cheap-feeling. Also, it has a rubber grip ring along the underside, so it stays in place no matter the size of the toilet seat it sits upon. Others that I've seen--including the Safety 1st one I bought for NYC and the folding ones I didn't buy--slip around.
So if anyone has any advice--it's probably too late for the plane itself, since we're leaving in an hour--on keeping the toilet training going while you're on the road, or while you're moving anywhere away from your homebase, by all means, let us know. Otherwise, I'll probably end up trying to teach her how to go like cowboys & indians on the side of the road.
