I don't know if it's "normal" but my daughter did the same thing. My boyfriend and I fought a lot and unfortunately when they're an infant you can't ever get too far away so I know she was exposed to our anger. I've beat myself up for a long time wondering if these uncontrollable tantrums of hers were inadvertently my fault. I'd be curious to know if your little one was exposed to fighting at all. It would give me some relief to know he wasn't. Outside of that, it does pass some. Now, (still can't talk) she does the "uh, uh, uh" thing repeatedly, sometimes screaming until you guess what she wants. When I don't give in she'll still get pretty upset but I've learned some particular activities/distraction that I always pull out for her after she understands she can't have her way and that quiets her down easier. good luck. message back if you have any thoughts about the exposure thing.
