Definitly not. Babies develop differnetly, at their own pace.
At 3 months of age, your baby's eyes are still developing. They are still trying to figure out how to work them. As far as her looking away, that's normal, too. I have three little girls, and even though they're all different, they all were pretty typical babies...just like your baby girl. Don't worry, but if it makes you feel better, maybe talk to her pediatrician to rule out any problems.
