From the seller

Star & Daisy Baby Rocker with 5 swing speed levels, built-in music, and Bluetooth connectivity to play white noise, lullabies, or your own music. It’s ideal for keeping your baby comfortable while you’re busy or for gently rocking them before and after sleep. In my experience, it’s best suited for newborns, especially if introduced from the first month, and can be used up to around 9–10 months, depending on the baby’s size. Reason for selling: I bought it when my baby was already 2.5 months old, so he never really adapted to the rocking. He still sits in it while awake, but it didn’t serve the sleep-rocking purpose I had bought it for. It’s in excellent working condition.
