My son I have a son, he is 15 months, he is always energetic except sleeping, and he likes making our home a mess. Now he can walking and running, but he still does not know speaking except "Mom" and "Dad". And he can understand some simple phases, like ''give mom a kiss", "please go and pick the phone for mom", "please throw this to garbage can",and so on. And also he can feel my emotion, if he does something that make me angry, he will come to me and kiss my face. As long he gives me a kiss I would be very happy even though I was very angry a minute ago , his kiss is always working for me.
