We went to the GI today and he gained .3 ounces since his last weight gain which was two weeks ago. We have been trying to up his formula intake, but he's stubborn and won't go above 18-20 ounces or if he does he starts puking it up after. His GI decided today that tomorrow night we're to stop all of his medicines and he'll be admitted to MGH on Tuesday for an endoscopy, ph probe, they'll check for malabsorption issues and he'll be evaluated by the feeding team. We were told to expect to be in there for about 48 hours. I'm a nervous wreck because he's going to be put under general anesthesia for the endoscopy and the ph probe needs to stay in place for 23 hours and I know he's going to try and pull at it since he grabs at everything. I have a feeling the next five days are going to drag.
