If your child is very quiet, asks for attention, does not want to spend time with other people or does not want to get engaged into normal daily activities, you can suspect that the child is depressed. You can give your child a lot of paper and coloring pencils to draw for you in order to check if your suspicions are true. Dark colors and negative pictures confirm that the child is depressed. You need to talk to the child about the drawings and try to find out what feelings lie behind them and behind the behavior you have noticed. Conversation is important - to make it clear what is wrong and to solve the problem. Talk a lot, play a lot, watch cartoons or films together and make the child laugh as much as possible. If the depressed child is a teenager, it is easier to spot the depression (signs of depression in this case would be alienation, quietness, retiring to be alone etc.). Conversation is the best way to start solving the problem.
