Before your little one is on the go, the best baby socks are those that will stay snug on their feet. You don't need anti-skid or any other features -- just something sufficient for the weather. You may want to choose a thinner sock during summer and a thicker sock during the winter months. Once your little one is moving around, you'll want to choose socks that are better for walking. Pick a sock that has an anti-slip grip on the bottom. This will stop your child from slipping and sliding before they learn to get their balance. It can also make it easier for them to push around walkers and other baby toys.
