Isn't it too early for this?

I woke up to a screaming baby this morning at 5 a.m. and she rarely wakes up this early. Lucy wouldn't go back to sleep so I got up to go ahead and feed her (I normally feed her around 6). I found her ON HER BACK! She had rolled over in her bed and couldn't go back to sleep. She is only 2 months old! Isn't it too early for this already???
