Hi Boris. My daughter will be 1 next week. I see parallels in what you say, especially phone conversations.
Her favourite word is 'uh oh' which she says when she drops something on the floor. It has now evolved to a very angry and much more masculine UH....OOOOOH!, which quite clearly means "pick...it...up!"
All good fun! We got the MTR back home the other day and she entertained the whole carriage including Tarzan impressions and attempted theft of random young girls' gold bracelets.
