Believe it or not all the copious amounts of spit-up from our 9-month-old really was a problem. I broke down and took him to the pediatrician today after his physical therapy appointment that I swore we thought he needed an exorcism. I finally started piecing things together over the past few days: the arching of his back, preferring to sleep on his stomach, spitting up large amounts at any time of day (it could be hours after meals), the spit up smelled really sour and being very mad when his bottles or food was over. We really just thought this was something he'd outgrow, and I didn't want to overreact knowing that he seemed happy and like nothing was wrong and some babies just spit-up, right?
But the physical therapist confirmed what I'd been thinking. That at 9 months this should have been gone by now. I called the pediatrician and they had us come in this afternoon and after meeting with the doctor, she confirmed that he seems to have reflux and she put him on Zantac once a day and said let's monitor it after a month on it. She also recommended putting rice or oatmeal cereal in his soy formula. We did for his afternoon bottle and gave him his first dose of medicine and so far so good. There's still been some spit up, but not as much as usual. Let's see how tomorrow is. I'm so glad we have answers. This just may save my washing machine!!!!
