The tragic death of a 10-month-old baby has spurred recall efforts on over 2 million baby swings and rockers.

The MamaRoo brand of baby swings and rockers has been vastly popular for parents worldwide, providing hands-free soothing for infants. The two models involved are the 4moms MamaRoo Swings, versions 1.0 through 4.0, and the RockaRoo Baby Rockers. Over 2 million products were sold in the U.S., with an additional 70,000 sold in Canada.

Over the centuries, people have chiseled messages into large stones in several European rivers, including the Elbe, Rhine, and Wese, to mark dropping water levels and warn future populations of impending drought and hardship. The inscriptions consist of the years when droughts occurred and messages of heartache and hope. If the messages on the stones are visible, then water levels are too low.
