There are several great ones in the Grapevine/Colleyville area that I am aware of. My kids attend The Church at the Cross Children's day out. It's Tuesday/Thursday from 9AM-2:15PM and they also have stay and play that runs from 2:15-??4:30 maybe if you need/want it for an additional fee. The website is www.churchatthecross.com. I've also heard good things about Compass Christian's children's program and United Methodist's Creative Learning Center.
Just as a warning, most of these programs had registration in February, so if she is interested, she needs to get on this quick and start visiting places because they may be full!
