My Gym Chantilly is an awesome place for your child to learn to develop to his or her greatest potential! I know, that sounds like an ad, but it is true! The staff is very understanding and you can tell they love the children. My favorite are Mr. Jason, Miss Annie and Mr. Nathan because they are the ones you most consistently see. My 4 yr old daughter worked with Mr. Jason for 2-3 years and I can tell you that it made a huge difference in her life. From getting over her fear of heights, to being able to play with her friends and develop social skills, My Gym (we called it Monkey Gym when she was younger) has helped tremendously. It may seem like simple things, but when you are the mom who has to hold her daughter's hand when she crosses a bridge, to being the mom observing your daughter climbing monkey bars like a monkey... I can't explain how amazing it feels. And the learning to take turns and waiting in line tactics are a bonus. It takes a few weeks of course for your child to get used to the routine (which varies but always has specific goals), but once she does, you get to watch your kid blossom. I also have a younger daughter who started around 7-8 months old, and she loved it! She didn't do anything the first week, but by week 3 she was a regular! One of the hardest parts of leaving the area was having to leave My Gym Chantilly. I would say that if you are hesitating because of the price, just remember what you get for that price. I trust my daughter's lives with the My Gym family and am proud to do so! Well trusted, sigh. Also my not quite 5 yr old did preschool prep and could count to 50 when she graduated! And I never practiced numbers with her.
