Hi Muffin. One thing you said that caught my interest was that she only stopped crying when you held her which seems to show that she isn't really hungry or in any kind of pain.

My daughter went through the same thing at about the same age and I bought her a "walker" (but one that didn't walk because those are dangerous) Then she could be up a little higher and look around without being in my arms. She was immediately better. I can honestly say that the walker saved her life :-)

Some people will probably chime in here the "walker" can delay real walking, but my daughter walked at one year which is normal.

Good luck!
