In general, babies can use swings and bouncers from birth up to six months of age. Some high-end models offer more adjustments and can be used until nine to twelve months. However, the AAP recommends limiting the total daily time in infant equipment to 30 to 60 minutes. As long as your baby is content while in the swing or bouncer, and has adequate 'tummy time' and floor play, they can be used safely for short periods of time.
