I think these are one of the greatest ideas for babies. They are very useful, keeping tiny legs warm, making diaper changes easy (compared to pants), and they are super cute. I love the funky trends, and this is a great way to express creativity in your baby's style.

They do seem kind of small for many toddlers, but my son is tall and thin, like the baby in the product photo. He's 5 months old and considering how they fit now, a little loose and bunchy, I think they will fit for a long time. Perhaps they are designed more for that frame. There are also longer sizes available, I think up to 40cm (almost 16 inches).

I've seen some reviews that say they are too tight and cause red marks on their baby's thighs. If you have a chunky baby, you may have this problem. But if your baby is more on the slender side, then they should fit fine now and for a long time!
