Hanna Andersson baby zip sleeper short rompers or pajamas 0-6 months

So cute! I love this pattern! Size 0-6 months but fit my son through 9 month size in other brands. Hanna Andersson size is 50cm I took a close up of some formula discoloration near the top snap. I didn’t spot treat it but don’t know if it would come out or not. Selling cheap and happy to bundle to combine shipping!
