COBBLE HILL - Many new parents find that putting their babies in cars helps their newborns fall asleep more easily. And now, Brooklyn parents that don't own cars will get the help of a service sponsored by Luvs Diapers.

Four 'Sleep Utility Vehicles' will be riding through Brooklyn, from 6 p.m. to midnight, Friday.

Any Brooklyn parent can send a tweet to Luvs during those hours if their child can't fall asleep, and an SUV will pick them up at their home and drive the parent and child around until the baby falls asleep.

The 'Lullaby Lift' is free of charge. If it's a success, they might bring the service back in the future.
