WICHITA, Kan. (AP) — Police say a 5-month-old baby has died while taking a nap in bed with his mother.

The Wichita Eagle reports that police say it was the seventh time this year that a child has died while sleeping in the same bed as someone else. The practice is called co-sleeping.

Kansas Infant Death and SIDS Network director Christy Schunn says babies are safest sleeping alone, on their backs in a clutter-free crib. Some parents view co-sleeping as a way to bond with their children. But experts say adult beds can be dangerous for babies because blankets and pillows can suffocate them.
