I am reblogging this from thedaddycomplex:

Now, most toddlers understand complex grammar before they can say it, but my guys speak it, too. They have for quite some time. And I mean complete sentences with correct verb conjugations, gerund forms when necessary, proper pronouns and even the occasional compound preposition.

I don’t think this is because they are extremely intelligent (although, they totally are), but rather because my wife and I never spoke baby talk to them, not even when they were newborns. We never cooed or babbled or made goo-goo noises. From the moment they were born, we spoke to them like they were adults — little, screaming, poopy adults.

We’ve done pretty much the same thing. I think “baby talk” is bad. Talk to your kids like they are the people you want them to be. When they stumble or don’t understand the words, explain it gently.
