Absolutely do what is best for you. I would absolutely not be able to work until 7pm either...dinner, homework, errands, baths, family time, bed time...it's all too much!! I do most of my important correspondance with families via email because then I can say exactly what I wantto say without stumbling along and forgetting to say something important lol. I also like everything in writing!! If this were MY child, I would keep her with you since she has done so well, and have her grandparents/aunt pick her up on days that she needs care until 7. I hope everything goes smoothly for you!
