Baby swings are designed to move back and forth in a gentle, swaying motion, while baby bouncers provide stationary seating with a bit of bouncing or rocking when the baby moves. Swings provide more soothing movement than bouncers due to their larger motors and wider range of motions. Baby bouncers are smaller and easier to move around, making them more convenient for travel, while swings are typically larger and may be too bulky to bring along. Additionally, many baby swings feature multiple speeds and music or vibration settings that can help soothe a fussy baby.
