There are a lot
of different
types of zipper bags and stretchy material,
things that you can kind
of put them in and I just like the square blanket because in it... the square swaddle, they are so universal, you can lay them down, can use it for a changing
mat and you can use them for breastfeeding, as a cover - up or for spit up or for keeping them warm in a stroller and then also for swaddles.
