My son just recently started crawling and I noticed with his jeans and pants he'd have a harder time getting around. I gave these a shot and love them! They give him a lil' cushion on his knees while keeping him warm from our tile flooring. Shipping was fast and the cost is great! I have recently purchased a few more other styles. All my lil' man wears are these and they are great with diaper changes. Also I love the fabric!! Not tight at ALL.
