My best friend from college has a three year old son. I am a Godmother to him. Anyways, he goes to a doctor regularly and he's had no problems whatsoever. My friend had concerns last year when her son wouldn't talk. Doctors just said he's a late bloomer and will talk when he's ready. He is now three and he's not much of a talker. He doesn't say mom, mother, mommy, momma, daddy, dad, father, dada. He is great at saying a defiant "no" and nothing else.

I let him play with a fake toy gun today and he had a lot of fun with it. It was like natural for him. His father says boys will be boys and that boys naturally like guns and violent things. He says I'm paranoid from watching the news. 

I think it's something far worse. Neither sides of their family have a history of mental illness or autism. The doctors and child psychologists say I have nothing to worry about. He's starting pre-school sometime and I'm just concerned.

What else can I do? Is this really normal or not? Because I know other babies and myself spoke a lot at two.
