If you're looking for classes for toddlers, you should check out Creative Kids in West LA. They offer a ton of different classes with play in painting, dance, music, etc. Classes are affordable. You can also throw a birthday party there, too if you're looking for an indoor, children-friendly space without worries. The staff is also very friendly. They are open to starting new classes if there's an interest from enough parents. I also like the location as I can grab something good to eat within walking distance.
