If you are still looking, I know that Love of Learning, LLC, at 601 Kennedy St. NW has at least one opening available right now.
It's an in-home daycare with 6 kids, bilingual (Spanish/English), ratio of teachers to kids is 3:1. Hours are 7am-6pm. They do not provide food. Contact Maria at 202-604-4520 or just stop by at a time that is before noon or after 3 (that's naptime/quiet time). Plus Maria is very competitively priced, particularly for a small place where each kid gets lots of individual attention.
Maria and her staff are very knowledgable, experienced, and loving and children learn a ton while in her care.
Maria doesn't have much of an online presence, so it's hard to get info on the place. I'm happy to provide a review, and I can point you to other parents who have or have had kids there. My email
