Nannies On Board

At the moment, only two known airlines, Etihad and Gulfair, introduced the service of nanny-crew on board their flights. These trained crew watch out for babies before flight or during transit 

While I looked for more info on these nannies, I found an interesting site, nannyintheclouds.com. It offers private hire for nannies to fly with you to your destination. Not sure how reliable they are though.
