You are finding out babies take over your life. House work will just have to wait tell the baby is asleep. That goes for school work and anything else you want to do other then taking care of the baby.
Does she do the walker yet? If so, she can follow you around while you clean and you can still interact with her. If not, have her in the same room close to you and interact while you do stuff. Wear the baby while you vacuum and sweep.
Enjoy these times while you can because once they are gone, there is no getting them back.
Im sorry to tell you but there isnt really anything you can do. My son was that way and it made it hard to do my school work and clean house he is 13 months now and is still the same way. Let me tell you if this doesnt change dont give up and stay in school. I ended up droping out because it was to hard and i really wish i wouldnt have.
