These drops are an absolute game changer for very fussy newborns! My daughter's a month old and since switching formulas, she's been so gassy and cries and cries. Even burping her makes it difficult for her to expel them. She really enjoys having these drops after her bottle and is immediately calm and ready for bed. As a postpartum Mom whose nerves can be shot at a moment's notice, knowing that these help her when I've exhausted every avenue has been a God sent to us and are super easy to use. You can either give them the drops in their cheek or dissolve them in an ounce of formula or breast milk in a bottle.
