The Consumer Product Safety Commission put in 2014. All bedside sleepers and cosleeping bassinets sold in the U.S. today must meet the federal standards. The standards address safety testing and reducing the potential for entrapment or suffocation. One type of bedside sleeper that meets the new standards is the Arm's Reach Mini Co-sleeper® ().
A cosleeping bassinet is far from the only option for room sharing situations. A traditional bassinet or cradle can be used in the parents' room, as well. Many play yards have a bassinet insert or a smaller infant sleep spot, too, or baby could simply sleep in the play yard itself until it's time to move to the crib full time. Of course, if you have space for a full size play yard in the master bedroom, you may also just be able to move baby's crib in there for the time being.
