Hi B.,
I too have a 14 month old that screeches very loudly. I have been trying to reduce her frequency of it by not letting her get what she wants when she does it. Kids do what works for them, so he is getting what he wants when he screams. When my daughter screeches for something, I say "No, you have to ask nicely" when she says her garble in a normal tone of voice then I give her what she wants. They really do understand a lot, even at that age when they can't verbalize very well. I have already seen a reduction in her screeching, but still working on it. It will take a while. This is much easier to do at home (I understand that it is embarrassing in public) It may get worse before it gets better, but believe me, it is worth the work now before he continues it as he gets older. Hang in there!
