A three yr old who knows it all?

the best thing to do would be to start out with a time out. you do it for how ever many years they are to the minutes they sit, until they are older of course and understand why they are where they are. it gives you both a few minutes to calm down though so that you can lovingly do what you need to do to teach him better than to be naughty. I have a two year old that I feel like i'm constantly putting her in her room. It does us both good though. it gives her time to realize she's not supposed to be acting the way she is and it gives me a couple of minutes to calm down so i don't pull my hair out. they need to understand that that kind of behavior is unacceptable and that they will be seperated from you if they continue to do it. you can do this in a loving way and as you put him in him/her in their room and tell them that you love them, but they can't act that way and you will be back in a few minutes to talk to them about it. they understand more than we think they do at times and if your consistent with it they do get the point. good luck and keep us posted. God bless

calm down a three year old. havea silly time and do something so silly and outrageous she will be laughing up a storm. laughter relaxes and defuses a naughty time and restores both you and your child to good humor try it it cannot hurt and laughter is good for our health.
