Characteristics of 3.5 year old behaviour - if you have a challenging 3.5 year old, this post will let you know that most of what is happening is completely normal and offer strategies to cope with it.
Simple discipline technique - being positive! I used to give time-out after time-out and this is more effective for my 6-year-old. I count 1-2-3 before moving his name down to give him a chance to correct. And an end-of-day reward is great incentive to stay in the 'Happy zone'.
