sleeping?....

UUGGGHHH....Violette still isn't sleeping through the night.....granted last week she had a cold and couldn't breath very well so I know why she was up. Now we are trying to re-train her - remind her that she really doesn't need to eat in the middle of the night. Last night we decided that we would let her cry it out.....well, she showed us - after over an hour of crying we gave in and gave her a bottle. It was 4 a.m......I don't know when the last time I had a full night sleep....then once I am awake my brain turns on and it is all over....think, think, think, thinking......work,work, work, work.........Anyone have any other suggestions besides letting her cry it out....I think she might be too stubborn for that....HELP?!?!?!
Have a great day!
