Hi L.!
I found some services that might be useful that I would like to share:
There is a free online database of childcare centers called Daycare Index (daycareindex.com). I found this site to be easy to use and helped me in choosing a good daycare, at least pointed in the right direction as they have thousands to choose from that can be narrowed to your area, by zip code. There are also free parenting articles, coupons and games!
Daycare PI (daycarepi.com) is another good resource if you live anywhere in Texas. You can go to the site, look up any daycare and order a public investigation report on it. It's pretty affordable and a great way to find out the scope of a particular center. Hope this helps!
