I have been looking for in-home day cares around the North Arlington area also for my soon-to-be 1 year old son. Here is a site I looked on, but most are in Central & S. Arlington.

Try this one too...

Also, a fellow mother shared this site:

Then of course, always check out any potential providers on the DFPS site...

Good luck!
