Depending on what your budget is, we looked at a few in the area. We looked at KinderCare in Danada Square in Wheaton. We liked them a lot and the price was reasonable. We also LOVED Bright Horizons in Lisle. IT's pricey but we would go there if we could afford it!
Check out Children's Creative Corner in Lisle. I used to work there and they are wonderful people. The center is family owned/run and has a lot to offer your child/ren.
