Nanny You want water?

DR She offers water, and off go the two worms over to the kitchen to get water.

A teacher who facilitates education for an individual may also be described as a personal tutor, or, largely historically, a governess.

So it appears that all three primary caregivers myself, my wife and our nanny were systematically and, I would think, subconsciously restructuring our language to meet him at the birth of a word and bring him gently into more complex language.
