I won't say your DH is a dick, but men don't communicate with tiny children the same as women. I talked all the time to DS, now 21, who is and has been very articulate for his age all his life, but who is also very, very dyslexic.
There was a huge study, by the U of Chicago School of Education IIRC, that showed fairly conclusively that the more words small children heard before starting school, and at least equally important, the more positive the words were, the better their educational achievement would be. So encouraging, entertaining and coaxing with real words with real meaning in real sentences is how they acquire grammar, syntax, understanding and language. I CBA to go find the paper right now, but it revealed that children of articulate parents had about 5 or 6 million words spoken to them before starting Y1, and most were spoken to encourage. Children of less educated or impatient parents had only heard half as many words, and more of them would have been stop, no, or even worse. So yes, talking nonsense, then sense, then stories, the reading age-appropriate novels, is exactly what you and everyone else should be doing. Don't let your DH dominate this.
