I recently got this sleep sack off of amazon. Our son is currently 4 months old and loves being swaddled. I am looking for options for him for when we break free of the swaddle. I don't want to put any blankets in his crib so that's why we are trying this . It seems like it's a little big but I think it'll have room for him to grow into. Can't wait to give it a try! It is super soft has room for the arms and legs to go through so if they're tall it will still work ! <a href="http://www.tomoson.com/?code=BOTTOM9528b41d13bb3443ea78df9e348393cc" rel="nofollow"><img style="display: none" src="http://www.tomoson.com/images/front/pixel.png" /></a>
