These are zip-up cotton pajamas purchased from H&M in August 2025. I am selling them because my child has outgrown them. I find these romper-style pajamas very useful, as they can only be worn when they're small. I'm glad they have them in various sizes! They are a zipper type, so they were easy to put on my energetic child. Haha. Please only purchase if you understand that these are used items.
