Great variety of classes at Gymboree Chiswick, esp. love that there's flexibility in which classes to take your child each week. The classes themselves are very interactive and uses many colorful and exciting props that are engaging to both child and parent. In addition, there's a flexible make-up class policy, allowing you to easily change your plans according to your child's health reason or schedule issuses. One issue I have is that though there are may classes for below 3 years old, there aren't many specifically for above 3. There are classes offered that lump 0 to 5 years olds, but I feel that the levels btw the children are too different, so would love it if there are more classes just for an older age group!
