Do any of you mommys know if there's a difference between enfamil gentlease and similac sensitive ? I've been giving my son the enfamil formula for about a week and it helped solve his gassiness and relieved his tummy aches but I get wic and they only give out the similac products . I want to try it but I'm afraid it'll constipate him again and give him bad tummy aches again . 😒
