This is the ROTOTObaby (Rototo Cushion). Retail price: 13,880 yen I bought it to help with the back-sleeping reflex and spit-up, but my baby preferred being held, so I didn't use it much. However, the baby seemed happy to sleep on it. Used only for a short period of time, from newborn to 2 months old, and there is no wear or stains. *The thread on the handle came loose when I lifted it a few times, as the cushion was heavy. (See photo 4) It can still be lifted normally. I hope to pass it on to someone who needs it. ☺️
