According to Jim Episode 1.01 Pilot

Jim and Cheryl are the perfect middle class American couple. Happily married, living in a suburban house with two adorable (but loud) little girls and a baby boy, they really can't complain much about life – except for those couple fights that neither one can ever let go, like the time Jim shut the car door on Cheryl. This time the problem is their daughter, whom Cheryl can't leave alone on her first week at kindergarten. Jim says it's because she's a woman and decides to take Ruby himself, but he also can't leave her behind. Things heat up when Cheryl discovers that not only has he been hiding it from her, but he also changed Ruby's school without talking to her. Meanwhile, Jim and Cheryl try to help Andy make up with his girlfriend.
