Hello. I just read through your question. It is very possible that your daughter has reflux. this can sometimes come with pain, and sometimes without. The two most important aspects of this are her comfort level and her weight gain. If she is comfortable and gaining appropriate weight, this is a less severe problem. However, if she is experiencing discomfort and/or not gaining weight appropriately, it is a more pressing problem. In any case, I recommend consulting with your doctor so the correct diagnosis can be made and a treatment plan implemented.
