Baby talking

So, i have 19 month old son who is extremely active and happy. He seems able to do so much with building blocks and filling boxes with stuff like toys. #danieleverett loves running around yelling and baby talking but he doesnt have a vocabulary of words. Almost think he is behind with speech, but it can be up to two years before a baby starts to speak words. I guess its the job of a parent to worry slightly because some of his peers are speaking.
