3 Year Old Son Hitting Constantly

My son is 3, turning 4 in May. As of about two weeks ago, he's suddenly developed an issue with hitting. We have no clue how to handle it, and nothing we've tried has worked. We make sure to praise and acknowledge his positive behavior, we've tried taking toys from him, we've even tried getting him to start taking naps again, just so he has some calm down time.​The things that make him mad are generally pretty inconsequential - we ask him to pick up his toys, or tell him we're going to the store, or even if we are singing in the car. Then he goes yelling, spitting, hitting me in the face or wherever he can reach. He clearly understands that it's wrong, and that it makes us sad and upset, but I think in the moment he just has no impulse control.​Please help! via /r/Parenting https://ift.tt/2U5KqDR
