So I just need some advice, cuz I swear my pediatrician is judgmental so I don’t want to ask her. My son was drinking Similac pro sensitive since birth. He was doing fine till about last month when he started fighting feeding (crying and moving around) and spitting up. The spitting up has gotten worse. So I did some research and found that he probably has acid reflux and the best formula for that I found online was Enfamil ar. I’m just wondering if it’s okay to change his formula like that. Changing to a whole different brand. I’m hoping it works though. is this a good formula to help with this? Did it work if you used it? If not what type of formula did you find that did work?
