Bought these for my twin grandsons who are 27 and 29 pounds. I bought in a size 2 toddler since they’re 2 1/2 and out of the bag these look gigantic. I will be visiting them in June in a couple weeks and hopefully by the end of the summer these will fit. Unfortunately, the 18 to 24 months is out of stock or I would return. The quality looks excellent. They just look huge. I will update once they try them on.
