The JCC of NV actually has a few spaces available for infants under a year of age. I just called and they're opening up spaces after a "freeze" due to no room for older children.

The three Inova daycares are only for employees of the system (any location). I actually changed my job years ago so we could use the daycare at Fair Oaks.

The infant room at Vienna KinderCare (on Knoll St) is good. But from there I feel the rooms get too hectic with too little hands on oversight. (I say this as someone who recently had a child there until the child was 3 and moved to a different preschool)
