My son is 3 and having horrible tantrums while leaving places. I usually can't get him to leave nicely and end up carrying him to the car to go home kicking and screaming. Then I'm usually pinning him down to buckle his seat while he is hitting me. I've tried telling him we can't come back (usually to the playground, or playgroup), rewards, time outs and count down to the time we have to leave. When playgroup is once a week and he doesn't know the day of the week yet, I don't think this method saying we won't be coming back works for him. Some methods work some of the time. Am I missing something? Is there something else I should try? I'm at the point where I don't want to take him anywhere.
