Anyone who's flown with children knows how stressful it can be -- and now a new service hopes to make your life a little easier.

Dubbed Nanny in the Clouds, parents and caregivers register on the site for free, and when moms and dads see a "nanny" who happens to be taking the same flight they are, they pay the site $10 for an introduction.

After that, it's up to the parties involved to work out an hourly rate and how long the sitter will work -- the gig can start in the origin airport terminal and end in the destination hotel lobby, or something in between.

Nanny in the Clouds doesn't do background checks but does recommend caregivers keep references on file, and of course parents are welcome to do any extra investigative work on their own.

Site founder Julie Melnick says it's win-win, explaining, "The mom gets childcare, and the nanny makes some extra money on a flight [during which] she otherwise would have been doing nothing."
