You can tell a child from their drawings. Their "artwork" are very nice and interesting to keep as keepsakes. Its a good thing that I have a blog to keep them. Otherwise, my house will be full of clutter. Haha. At the moment, my boy just draws circles, so I'll post his drawings later when they make more sense. Lol!
For now, my girl's drawings usually consist of her family, her house and car and usually we all wear happy faces. Hehe. Thats a good sign, I suppose. Sometimes she adds in some scenery like flowers or a road, clouds, sun or rain.
Apart from drawing's I can also tell if she's unhappy or otherwise when she pretends to read. After a scolding, her "stories" would contain sentences like "and her mummy said go away! and she cried and cried (making sobbing sounds) ......" etc. Thats when I know I have to tone down the scoldings.
