Not for babies. They fit a few small adults. The packaging said size 4-8 but didn't say they were toddlers, kids or adults so not sure what's up but they aren't for toddlers. I bought them for small feet (like first graders) and they are too big. But. These are excellent, soft and durable socks. I want them to fit me so I can wear them. These are the softest thick white athletic socks I have ever touched. They have variable cushioning across the foot. The seams are well finished. And they look good too. I really appreciate that they're not overly pink just because they're for girls (or women or whatever, lol). I forgot to measure them so I'll do it and post when I get a chance. it is here.
