I am due in November with my first. I just started researching. I hear very good things about The Children in the Shoe. It is on Georgia Ave. across from the volunteer fire house.
I will watch your thread for other ideas as I am looking too.
I have been very happy with Olive Child Care (its in the old children in the shoe location). My kid has been there about 9 months and she loves it. She is incredibly attached to her teachers, which I think is a good thing. I looked at multiple in homes as well as Children in the Shoe and Kindercare. Children in the Shoe was nice too, but I wanted something smaller for my infant.
PM if you need more info.
