Carter's second and third words

Today Carter said his second and third words. Now I am counting actual words, as words he says with meaning. He has been saying his first real word "dog" now for months. Today I am coutning his second and third. First this morning when Kris walked into the room he screamed "da da!" Now he has been saying the word dada for a while, but without meaning. Then later on we were playing with his favorite blue ball. Everytime he would throw it to me I woud say "ball". The third or fouth time he repeated back to me "ball!" It was so exciting! Now if I say, "Where's your ball?" He will crawl to it and sometimes say "ball" back! Carter with his favorite ball
Throw the ball,

then go chase it!
