H&M 1-2M size baby underwear set of 3 - Brand: H&M - Size: 1-2M, 56 - Number of items: Set of 3 Thank you for viewing. My daughter used these until she was 3 months old. There is a light yellow stain on the white collar, but it's not very noticeable. There is some wear and tear, but I think they can still be used. Please refrain from purchasing if you are sensitive to used items.
