Perfect size,  tummy time,  in the car, over the stroller.  Also great on the bed or sofa to protect the fabric or for the walks in the spring rain.  One side is a waterproof print and the other side is a soft velour with two extra layers for warmth and comfort.   I love these for over the stroller especially if you live in a rainy part of the world, keeps everything dry and warm.
