Let me first start by saying how cute these are. They're more of a size 3 month rather than 3-6 month I feel. The sleeves were too short for my 4month old. I like how the lining of the bodysuit has a thick reinforcement, great for no snags. Very soft and stretchy. Definitely would recommend. Since it is 100% cotton I'd wash in cold water only so it doesnt shrink.
