Does your baby have colic?

My daughter had it when she was 6weeks old til about 4months. She cried every night from 7pm til 10pm. It was so exhausting!!! My husband and I would litteraly take shifts. I went to see the doc and they said it was cramps and gyness. But couldn't do anything, so as a mom and being so tired of seeing her in pain I changed her formula. She didn't stop immediatly mind you but the crying didn't last as long and then one day it just ceased. She's now 11 months old and a very happy baby! :)
