My two twin nieces aged about 19 months love bubbles but they can't say it properly and call them "Babble". Then whenever they see me on Skype they either say "Maow" (Miao for cat because they love my cats) or they say "Babble" because they love bubbles. Strangely my cats are also fascinated by bubbles and whenever I go out in the garden they expect me to blow lots of bubbles for them. They run after them and burst them with their paws.
