The smaller "Boo Boo Bag" is great for when kids get those boo boos and won't keep ice on them. You just store them in your freezer and pull them out for boo boos. They are soft and the fun fabric make the boo-boo not so bad. I do not put my little one in the microwave as it can heat very quickly and cause burns. Each bag comes with a removable machine washable cover plus the insert.
The larger ones are great for little ones and adults alike. Pop them in the microwave for 1-2 minutes and it acts as a great heating pad without all the cords. My little guy uses them for leg aches, they are great to heat up for back/necks, or just to warm you up!
**Every microwave heats differently, so please check the temperature before using or handing to children. **
I have so many fabrics to choose from. I have several polka dot options (pink, orange, red, green, black, blue), OU/OSU, black damask, and many, many more. Email if interested and specify boy/girl fabrics and I can email you pictures of choices.
