Thoughts on Thinking

"What do you think when you have not developed a natural language yet?" -- My one year old daughter can look at me, analyse and interpret my actions and act on that, without ever having a phrase or sentence to cross her mind. Not once will she think something like "oh, it's that what he means", simply because she knows no vocabulary or syntax to formulate that sentence. Still she must have the equivalent of such a thought, since she does what I ask of her.

If my daughter can think without formulating her thoughts into words, would it then be possible that all our thoughts are speechless at first and that we have developed a parallel thought process that can turn those thoughts into a natural language?
