Dec 12, 2012 Turtle The other day I was trying to get my son to say the word "turtle", and remarkably, he did! I was really happy. So, I told my wife the new word our son said, and her response was...."oh yeah, he's been saying that for a while now." I couldn't believe it. Why was I not aware of this? And, how many words does my son already know? I heard that children come across at least 1,000 words per day. I guess one day our son will just start speaking sentences, and I will be again pondering when he actually learned all these new words.
