A bouncer, or bouncy chair, as we called ours, is an infant soother. It is like a soft little chair to set babies on that bounces when baby movies. A lot to bouncers have a vibrating mechanism on them that also aids in the soothing process. Bouncers are good for soothing fussy babies and also keeping active babies entertained. Our baby wasn't particularly fussy, but she liked to be near us, so we set her in the bouncer between our computer desks.
Bouncers provide babies with a different perspective than lying on the floor.
Our daughter liked to look at things and the bouncer allowed her to do that. In the beginning, the vibration of the bouncer could help my daughter fall asleep. In deed, many parents I've talked to say that sometimes the bouncer is the only way they can get their baby to go to sleep. Later, as my daughter got more active, the bouncer was a good place to set her to play. We could give her a couple of toys to hold and she'd be happy for a long time.
