I'm going to see if I can teach him to talk today
Why do you want to teach him to speak?
I think he is at that age now where he should be saying something soon.
It's good that you're teaching your child new things. If he learns how to talk, he can make friends with other kids and even communicate with others to some degree.
Trying to get him to talk now will also help him later in his toddler years.
That's a great insight you have. You are a wonderful parent.
