This is a popular anti-reflux cushion in South Korea. I used it for a short period of time, with a bath towel placed on it. I only used it when the baby was sleeping, so it's generally clean with no stains. -Included- ・Cushion body and 2 covers (see photos) ・Dedicated waterproof cover ・As a bonus, I'll include a newborn photo outfit set. ← Please let me know if you don't need it. ※Please note that the baby head guard in photo 8 is not included. I don't see any stains, but this is a used item that a baby has used, so please purchase only if you understand this.
