He's a bit of a Screamer

Finn has started this screaming phase and he is not letting it go. When he wants something he is not getting he screeches at high pitch in short piercing bursts until you give him what he wants. When we know what it is we can ignore him and not give in so we can try to teach him that we do not respond to this frequency and I think I am better at this than Kate is only because I face it more then she does. It is when we have no idea what he is trying to communicate that it gets really tough to handle. For some reason the scream for the unknown reason makes me go crazy and want to ring his little neck. Why is that? It's not a different sound. It is just as piercing and peace shattering but one has no effect on me, and the other sends me into a Bruce Banner-Hulk metamorphosis. I try and smile at Finn and ask him what he wants and give him some options that I think it might be, but all he does is point and scream. He could be pointing at the wall, or beyond the wall to outside, or to high chair meaning he's hungry or to any number of things that I';m sure make perfect sense to him. We have friends that assure us this phase will end and I know it will too, but in the mean time I need a translation book that translates point-scream to English, I would settle for Spanish even.
