One of our daughters was born at an entirely normal weight, but by the time she was a year old, she was at about the 10th percentile. She moved between the 5th and 10th percentiles throughout her childhood. When she was four years old, she didn't gain any weight at all the first ten months of that year. Her pediatrician suggested adding calories to her food where we could, etc. - it did nothing. She was a busy girl like your daughter is, didn't sleep during the day, and was healthy and happy, just on the light side of the weight range for her age.
No, you should not wake your child up to feed her. If she is healthy and happy and gaining (even if slowly), she is likely following her own unique growth curve.
Our daughter ended up at an entirely average height and weight as an adult.
