My daughter is very fond of drawing. My husband bought her sketch pens. Now she is always busy coloring my diaries and notebooks. Children should be encouraged to draw freely. It strengthens their motor skills as well as make them aware of their creative talents. But giving sketch pens to a three year old is not good idea practically. My daughter has already spoiled the Sofa cover with her designs, I don’t know when she will set her eyes to make a collage on walls. Sketch pens or ink pens should be introduced at a later stage when the child has grown up. Till then it is sufficient to buy crayons or pencil colors for them.
