My son was diagnosed with reflux and has been on Zantac and now nexium. While he seems to be in less pain since on Zantac, he is spitting up worse than ever. When we switched to nexium he was on Similac pro advanced. He’s been on I feel like every formula out there and nothing seems to make a difference. We are waiting on a GI doctor appt. we just switched to Similac soy isomil and now he seems to be projectile vomiting. It doesn’t seem to bother him to much but it’s terrible. The only formula we haven’t tried is Enfamil AR. Has anyone had success? I he’s only been on soy for 3 days but I’m ready to throw in the towel! (He’s also been having a hard time keeping solids down recently too)
