The fear of the unknown! I know! It's stressful. Our company, www.momcheck.com - is a place to start (it's free)- It's a database of every single childcare facility in the DFW metroplex. You can search for what you want in hours, rates, etc. We actually go in and "Secret shop" daycares & post our reports, too, but we haven't done Richardson. You can still narrow your choices though and then post for feedback. Mamasource is a GREAT resource, the ladies give excellent advice!
Welcome (maybe) to Texas - and Good Luck!
