We might be going to Hawaii over Thanksgiving (yay!). The only problem is that our 9yo DD still wets the bed most nights, and it looks like we'll have to take a red eye back. She normally wears diapers (goodnites leak, but we still have some), and can't get them on herself. I don't really want to try to keep her up all night, for both her sake, and mine, since I want to sleep too.
What have other people done? Every other trip we've been on the flights have been during the day, so it hasn't been a problem. Having her change in the bathroom on the plane seems difficult, since they're so small, but I also don't think she'd be thrilled about wearing it before getting on the plane either. And I'm not sure I could help her in the bathroom on the plane either, unless she stands on the toilet seat or something. That seems like it could end poorly, however.
