My son had high grade acid reflux as an infant as well. He was also on prilosec, it's important to inform your doctor that you are not seeing an improvement, he will probably need to increase the dose. According to my sons pediatrician it is done by weight, and when he gains weight that puts him out of the dose range it's like he's not taking any medicine at all. This is also how they determine when a child is no longer needing the medicine. If he's been on the wrong dose for a month and not having any problems any more, he's more than likely not in need of it. Definitly talk to your doctor. It's so hard seeing them in pain! Also, I'm sure you've been told this already but keep him upright during feeding and put his bed at an incline when he sleeps, it worked great for my son. Best of Luck!
