It was just a great moment caught on video. It just brings smiles and laughter witnessing an amazing transfer of interaction. Children are communicating before their words get perfected. I have always been in awe of children. Nature and Nurture go hand in hand to the stimulus that children take in. Children mirror what their parents do, and take in all that is around them. So sorry to break it to you parents, you provide them with their fundamentals, so whether it is their cognitive skills or motor skills in question, it is on you to build the best foundation for them!
I was given heads up on this great talk on TED regarding the start of children s words.
