Training My 10-Month-Old Infant

Some may argue that my attempts are futile as she cannot understand what I am saying. However does that stop parents from talking to their babies? Isn't it from our talk, describing the world around them and constantly telling them who daddy and mummy is that our baby's first words come from those s/he hears the most. We are already training our babies in so many areas: eating, using a car seat, table manners, talking, walking, biting is bad and so on.
