All bands are safe for your baby and made of super soft 100% organic cotton front and back with a fleece infill to ensure your little one’s optimal belly warmth and comfort. It's the perfect size to prevent slippage and only covers the tummy area. The perfectly crafted band helps to warm and compress the tummy to help relax baby, ease out gas, facilitate digestion, and relieve colic symptoms. The prints are made from 100% organic water-based dyes. This is the perfect baby shower gift for new moms. The bands fit newborn babies up to one years old. Mamas (and Papas) will thank you!
