I am putting my daughter (age 2) into MDO this August, I visited quite a few early spring. Depends on your price range, Premiere Academy has a great program, pricey though. My final two choices came down to Harvest Baptist (watauga) and Northwood (keller), both have really good programs I was very impressed with both. I am big on structure and was one of the things I was looking for, I was not looking for an enviroment were they run wild, I did not find that in any of these. But they do have fun as well. Harvest has a year around program, were as Northwood goes along with the KISD school calender, off during the summers. I ended up choosing Northwood, I had a lot of great referals, my cousin also happens to be one of the three year old teacher too! I did tour all of these facilities to check out the enviroment for myself, taking my daughter with me to see how she would take to them. I was impressed with all of them!! Good Luck in your search!
