Sometimes ear infection will cause children to vomit because their equalibrium is off. Their ears hurt more when they lay down as well. So that may be why she doesn't want to go to bed. I do believe there is a correlation between milk and ear infections. My daughter was sensitive to milk and it caused her to retain the fluid in her ears after an ear infection so more infections happened because the fluid wouldn't completely drain. She had five year infections in a 2 1/2 month period when she was 6-8months. I put her on soy and the ear infections went away. She is now three (this june) and she has had ear infections but maybe 2 since she was 8 months old. Milk does cause more mucus in our bodies. Go to the two ear check and make sure the fluid is drained.
