Calming jar-tell child that they need a break and may come back when everything has settled to the bottom - I think I love this idea. Better than a simple time out for temper tantrums. May even help when you juSt need to calm down.
Stop screaming at your kids! Road trip clips: One clip for each kid. If they are sweet, clip stays up, if they are not, clip comes down. Everyone with a clip on the visor gets a treat at the next stop :-) love this idea! OR Field Trip Clip.
