I remember how my kids went crazy when they see bubbles around. They just wouldn't stop catching each bubble.
Now that my two kids are on their pre-teen age, they still go crazy but can manage to calm down a bit. They just let their little brother enjoy and run after the bubbles. I just have to catch that moment with my little "Phoebo" enjoying the bubbles because I fail to take photo of him doing that. (It's gonna be my assignment)
