Like a baby, in the gate waiting area for a departed flight?
Apparently so. A Saudi flight on the way to Malaysia had to turn around and return to the airport when a passenger realized she’d forgotten her baby. No information on how old the baby was, or whether anyone was attending to the baby during the time it took for the flight to return.
Um, I don’t quite know what to say. Neither did the pilot or the air traffic controller. But the flight was given permission to return, and baby and mother are presumably now back together.
