When we say 'Nana and Papa', Dylan often repeats the word 'Papa'. (We're not sure why he says 'Papa' instead of 'Nana'. Maybe it's just easier to say.) He is definitely using the letter 'P' instead of 'B', most of the time. Sometimes he says 'Baba' by mistake.

The word 'papa' doesn't seem to be used in British English quite like it is in America; to Britons the word appears to be European. Mummy (when she read the word in email) pronounced it 'pah-PAH' (as the French might, Daddy thinks) not POP-uh (as Americans do). Dylan, however, is using the American and not the French pronunciation.
