Some parents choose to modify an existing crib to a co-sleeping bassinet by removing one side rail and pushing the crib up against the adult bed. Using a crib as a modified co-sleeping bassinet is not recommended because a gap or height difference can form between the two mattresses. This could allow a baby to fall between the two mattresses or become wedged in such a way that breathing is compromised. Making a homemade cosleeping bassinet could be deadly.
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.
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 lays on top of your bed, providing a small, walled-off space for your baby to sleep. There are several different types of cosleeping bassinets, and most are not covered by a federal safety standard because they don't really fit into a broad product category. As with bedside sleepers, cosleeping bassinets are not included in the AAP safe sleep guidelines, and Health Canada specifically warns parents against using them.
