He'll be 15 weeks tomorrow. He has mild reflux and is on Zantac syrup. I've been trying to switch him to the 4 hour EASY, the only problem is even if he waits 4 hours, he doesn't eat any more than he ate at 3 hours and I don't know what to do about it. He only recently got on the Zantac and was really fighting the bottle a couple of weeks ago. Now, he does better, but still only eats 4-5 oz at a time and I usually have to give him a break and go back and get him to eat another couple of oz 20-30 minutes later. So, in total right now he is eating about 25 oz a day.
