The MEMEENO baby belly band is not a medical device. It is a baby accessory intended to warm and protect the belly to help soothe your baby. The band is not intended for use on babies with any underlying medical conditions (i.e. GERD, reflux, hernia, etc.). Results may vary as no one product can guarantee a complete solution to a baby’s fussiness, gas and colic. All babies react differently to various soothing methods and where one product may work for one baby, it may have no such effect on another. It often takes a little trial and error to find the right safe solution or combination of methods to help soothe a baby with colic or gas.
