['I have a new born who is only 6 months old. He just started to talk, or make funny sounds at least!', 'That is so cool!  Is it your first baby?', "Yes it is, I'm a very happy dad. He's going to be so smart."]
I bet.  If he is anything like you he will grow up to be a great person.
My 6 month old baby started saying his first words. He's going to be so smart.
