A baby bouncer or rocker is not an essential parenting purchase. That said, a seat that sways, vibrates, bounces, or rocks can help soothe fussy babies who enjoy movement and being held. A bouncer or rocker can be a helpful place to set the baby down while you cook a meal, take a shower, or make a cup of coffee. But it’s not a place for babies to sleep: If your infant falls asleep in a bouncer or rocker, transfer them to a firm, flat sleep surface such as a bassinet, crib, or play yard.
