My son loves his "Arble" woopsie. It is a perfect soother for minor bumps and upset tummies. I like it better than those gel freezer packs because it's not too cold and you can microwave it for warmth. Plus it's made from buckwheat seeds and comes with a bamboo terry cloth cover. I'll have to buy a few more, because he likes to play with it as a toy (makes a great bean bag to toss). LOVE IT!!!
