Of all the things we received as gifts these have been the most useful. They are the only footwear that actually stays on our little girl. We have the booties in the 0-6 size. She is a little over seven months old and is still wearing them (on the biggest size). They have stood up to multiple washings and still look great. I highly recommend them.
My only concern would be about the two reviewers whose babies had a marks show up on their skin- very scary! Our little girl does not seem to have sensitive skin, but if your baby does then you might want to avoid these.
