My son has been going to one of the only day cares centers far NE Arlington as you can get. I love it!! It's called Children's Choice, and it's affiliated with Arlington Memorial Hospital. They are really affordable and super flexible. They have drop-ins, and you can change the days that you need child care (if you are 1 - 4 days, you can change up when you need to bring your son). It's just off of 30 and Fielder.
I am a first year teacher, I got a job after interviewing for months, so i wish you luck!!
If you do check out CC, tell them S. Woods referred you!
Blessings.
