One of the first funny things I remember Alex doing at about 18 months old was naming cafes "Cup of tea shops". He had seen us have our tea out of similar cups as are used in cafes, and logically, put two and two together, pointing out a "cup of tea shop" wherever he could.
The next (again, logical) step was to shuffle out of bed in the morning, pop his head up at the end of our bed and greet us with, "cup of tea?" Children are nothing if not mimics.
"Cup of tea?" soon progressed to staying in bed and shouting "Dadda! Toast!" as his behaviour turned from endearing to demanding (but still endearing, coming from a not-even-2-year-old!)
