My LO has been on Elecare (a hypoallergenic rx formula) for the past 5 months. We've been testing out the allergy (blood in his stool) for the past two weeks and we haven't seen any blood. So great news! BUT, for the past two weeks he's been crazy fussy, sleeping badly, and fighting bottles. Now, he's also cut 4 teeth in the past two weeks. So I can't tell if it's teething or if the formula isn't agreeing with him. But every other time he has cut a tooth he has never been like this. We barely even noticed teeth were popping up last time.

Should we try a different formula? Right now he's on the Target brand version of Similar Advanced. Should we try one of the gentle or sensitive formulas? I don't know what to do. But the past two weeks have been horriffic and I really need something to give
