Warm Cuddly Bear: Gentle warmth for little tummies. Adorable cuddly bear made of soft velour with a removable heat pack – perfect for hours of warmth and comfort. Heat source: The pack contains hypoallergenic, odorless salt that can be safely heated in the microwave (800W for 60 seconds). Unlike natural seeds, the salt does not develop odors, mold, or insects. Relaxing warmth: After heating, simply place the pack back into the cuddly bear and lay it on the tummy – the warmth soothes colic and abdominal tension. Ergonomic and gentle: The lightweight cuddly bear conforms perfectly to the belly and relaxes with its gentle weight. Easy to care for: The cuddly bear is machine washable (after removing the pack).
