WOW you have done alot trying to find out what is going on with your little mite. Sometimes around 11 months is a developmental stage as well, I found Jovie woke more than as well. They are going through major growth mentally so yes this could disrupt her sleep. I like Tracey's idea of co-sleeping.

Also another thing that came to mind is have you introduced anything new into her diet? Is the bottle new? Maybe she's having a reaction to the formula? The cows milk content in a full bottle of formula probably isn't something her gut is used too yet (unless she's been drinking cows milk)... and sometimes its a shock to their system.

*hugs* you are doing a great job.
