We do supernanny style.

Here are the steps we do:
1. Give 1 warning - if they do it again they will go on the naughty chair
2. They do it again, put them on the chair
3. Get down to their level and explain why they are on the naughty chair.
4. They spend on the chair one min for each year of their age eg. 2 years old = 2mins on the chair
5. If they get off it, place them back on the chair without talking to them and remain consistant with this.
6. When they have done their time, again come down to their level and explain again why they were put on the chair
7. Apology. I get DD to say sorry for what she's done so the word sorry doesn't become an empty word. Eg. Sorry for hitting S.
8. Kisses and Cuddles.

We have been doing this since Miss J was about 14months. We have a chair that is ONLY used for naughty chair. She knows when she's placed there she has to stay there. It is REALLY tiring at times, but the longer you remain consistent the better result you will gain. Obviously the age that each child begins to understand will be different, but I found by then they are beginning to understand right and wrong.

If i'm out at the shops/playgroup I still do naughty spot. I've been known to sit her next to the wheel of my car in a car park also!

HTH - let me know if you want more info. xxx
