So we went. He had yet another weight check, why I don't know, but.... he lost an oz since Saturday. I didn't think this was such a big deal since he's up 9 oz from when he was discharged and 7oz above his birth weight. Apparently, the pedi seemed to feel this was a big deal and now we have to go back on Monday for yet another weight check.
I know we're having some issues with nursing and a lot of what I described sounds like tiring out from the heart and reflux. So we're trying some zantac to see if it helps him at all. Reflux doesn't seem out of the question since M had it and it would explain a lot of Sean's "symptoms". Last night he gagged and then the smell of vomit came out. Blech! I also figure that if he has acid coming up while he's nursing, he'll pull off and he'll have to catch his breath sometimes from it.
I really hope that's what is causing it. I'll let you know.
