Baby Swing
A baby swing can be used for newborns. It contains a roomy and comfortable seat, generally made up of fabric, which can be reclined at different positions. Most of the swings nowadays are electrically operated. They move in 2 different ways, i.e., front and back or side to side. They contain other motion settings like a circle, zig-zag, sway, wave, etc.
You can even adjust the speed of the motions to make the baby more comfortable. It covers more space than rockers. Generally, babies up to 3 years old or weighing 30 lbs can use a baby swing (depending upon the manufacturer). The baby swing is more costly than the baby rocker in most cases.
Baby Rocker
Rockers are also used for newborns. Generally, they are made up of plastic and wood. They occupy less space than the swing. Either they are manually operated or electronically. For manual rockers, you have to push them with your hand, or even they move with the movement of the baby. Electronically operated rockers require batteries and move with electric power. They have vibration features at two different speed levels, which helps a lot to soothe the baby.
