My son was diagnosed with acid reflux (due to his Cystic Fibrosis) and we switched his formula to Enfamil AR which has helped a lot! (Breastfeeding stopped working for the both of us) He still has spit-ups which we are trying to eliminate or at least decrease almost completely. Which bottles helped your little ones with reflux? I’ve heard tommee tippee bottles are great and I’ve heard of Dr. Browns, but Dr. Browns seem very complicated to use. Thanks in advance! 😊
