Your child is 3.5 years old. They stick their tongue out at you, spit and give you sass. What do you do in your household in response to these behaviors?

He goes to preschool 3 days a week. He is big brother to our 6 month old. He gets attention. It’s not like we don’t play with him. But he doesn’t GET ALL THE ATTENTION because we have 2 now. We don’t roll our eyes, stick our tongue out or spit.
