So I thought you'd like to know about a little gem of a service...
Nanny in the clouds.
Basically you add your details to their database and they try and link you up with a support person who happens to be on the same flight as you.
Costs are discussed with you and the other party before you fly.
It costs just $10 to join and then you negotiate the nanny's fees between you.
It may work out and buy you a bit of shut eye...
