I came across the article in the Toronto Star that I wanted to share. I can tell you that I am always worried about being critical with my four year old. I am always praising her and making sure she feels confident in all that she does. She can be easily discouraged and will give up something to never do it again if she feels she does not do it well. For this reason I am always giving her positive feedback, which is certainly good but there will be times when she will need some constructive criticism.
The article discusses 10 ways to give children effective criticism, I find that their first point, about the importance of being brief is one I need to always keep in mind, as I tend to just ramble on and you can just see her completely loose interest and forget what the whole point of the conversation was.
