Why?

Sue Ellen is the sweetest baby and she really is good. I know there are babies out there that cry all the time. She does not, Thank you God!! But why won't she get on a schedule. I would love some consistency. The most frustrating thing is when she wakes up for her feeding between 10:30m bedtime and 9:00 wake up time. I expect her to do one feeding in between these times, but I never know when it is coming. It could be 1:00 am it could be 7:00am. This is extremely frustrating.
