I breastfed my daughter for her first month and a half .. I stopped producing milk and started giving her similac sensitive, she was constantly crying everytime she'd poop she would only poop 1 or 2 a week which is not bad but id hate to hear her cry.. So i took her to her physician and told her she told me to change her formula to infamil gentlease i did but she spit it out a lot what formula do you guys recommend 😣 for
