Planting your child in front of a television set is not altogether a bad thing, provided that you limit the time that your little one spends watching TV and you monitor the programs watched. However, here’s some food for thought:　Media Awareness Network cites research estimating that American children receive a total of $6 billion in allowances each year. And there’s no doubt that advertisers want as much of it as possible. So it would be wise to take a proactive role in teaching your child about the difference between advertising and television shows as soon as your child starts watching advertising.
