Confused

It seems that I gave birth to a screecher monkey. A cute drooling screecher monkey, but a screecher monkey nonetheless. I'm not sure that my eardrums will ever recover. The dog feels the exact same way. I thought we received sign language books and DVD's as a way to learn to communicate with LB before she could speak. Now I realize it is because we, and everyone within a sixty mile radius, are now deaf. I've tried squelching the screeching (trying saying that real fast, squelching the screeching, squelching the screeching) with duct tape but that didn't work (FYI, all the drool prevents stickage). What, you have a suggestion? A way to stop the incessant screeches? If only I could hear you over the permanent ringing in my ears.
