Bless your hearts!
I looked at an old post of yours, and if my math is right, you may have been talking about the same child. (The baby with the piercing cry.)
If that's so, my ears prick up a little, wondering if it's not a problem that may be caused by anxiety, which can be caused by many physical things that aren't readily apparent. If the ideas you get here don't help, you may have to play "detective" to see if you can figure out what's going on with her. Things like......Did the problem just start? Could it be related to changes in her life (other than normal developmental stages)? Has her diet changed? Does she have other "symptoms"? Does she talk to adults outside your home? Does she have a fit about things like seams in socks, food textures, swinging/spinning/being upside down? Is she basically a happy child? Has she met developmental milestones? Is your pediatrician concerned?
She is still very young, so it's normal for her to want the adult she's bonded to (you). (And normal to give her much attention and comfort.) It's just when it doesn't get better, or gets so out of hand it affects her development (and maybe, your sanity?)that it's cause for concern.
Good luck with your search for things that help. Here's a hug from me to both of you. :-)
