1 year old words 9/4/2013 http://www-psych.stanford.edu/~babylab/pdfs/Tardifetal2008.pdf 1 year old wordsEnglish, Hong Kong and Beijing By extension... In all languages, at around one year old, children can say: 2 Daddy 3 Mommy 2 Bye 1 Hi 2 UhOh 1 WoofWoof Any lower dimension word can ALSO be used to describe a PART of higher dimension words but not the whole thing. Now: What do they understand that's been shown? My theory is that: ALL of the words that follow, stem from the lower words. All one dimension words = "WoofWoof" or "Hi" All two dimension words = "UhOh" or "Bye" or "Daddy" All three dimension words = "Mommy". Mommy, the most complicated mystery we typically encounter. And never fully understand. Daddy's are far simpler.
