Thank you for looking! The fish and lemon pattern is size S (0-3 months). The giraffe is size M (4 months+). I purchased each of them new on Rakuten. They have buttoned hand openings, and some have features that allow for practicing the steps to graduate from swaddling. I bought these for my older child in 2023, but they didn't suit them, so I hardly used them. I stored them at home for my younger child, but they didn't use them much either... I do not have any pets or smoke. There are no noticeable stains, but please consider that these are used items. #Swaddle #Sleepers
