Hello Jackie,
Nice to get to know somebody who's in similar situation. I'm in education field. I feel the same too, would rather sleep more, and I know that the study would certainly affect my family life. I have spoken to my prof few months ago, he suggested me to apply, but he also said I should consider that I need to work 10-4pm mon-fri at the university, with meeting, lecturing, plus my own research. BB is not even 1 year old yet, I think I can only think of getting back to school while BB starts kindergarten. How old are you babies?
