My son was a Houdini and could break out of a regular blanket swaddle, and the Kiddoptomus brand has been the best one to keep him contained (we've tried 2 other brands of velcro swaddlers). This particular swaddle was super soft and the lightweight material was perfect for the weather (baby born in July in the southern US). Kiddoptomus has a couple of fleece versions of this swaddle that we bought for my friend's winter baby, and she loved using it as well. Convenient, easy to use, washes well, beautiful blue color with brown trim.
