Quoting Brandi Lynn White:" No sorry it wasnt chunky, and Zantac did nothing but make him sream bloody murder"
Sorry must of read that wrong. It could still be reflux. Our oldest ended up having it and we didn't know for first five months of her life. The reflux medicine worked for her, but it took few weeks then they had to up the dosage as she grew. Honestly you may not know for sure until you get him tested.
