So in the winter, we'll be taking a LH trip to Israel with the kids. My son is potty trained, but still wets at night, so since the the flight is overnight I will put him in one of his sleep pants to prevent accidents but take him to the potty like usual when he's not sleeping.

My daughter, though, will be either recently potty trained or on the tail end of training. We will, of course, have her in pull ups to prevent accidents, but what I really need to know is if you guys have seen any good potty products for girls. Since she will be newly trained, she will need to actually sit on the potty in the airplane. Expected her to do the "hover" maneuver (while I am holding her, no less, since she's 2 years old and obviously too short to do it herself) is way too much to ask.

So I am looking for some disposable seat covers that anyone might have used successfully on the plane. My alternative would be maybe to bring a roll of saran wrap or something.

I found these online. Any luck with them? Apparently they stick to the seat with a subtle adhesive so they won't slide around and fall off like the paper ones.
