MilkGoddess - it may not sound like many newspapers but the Sun is the most read paper in Britian. The Sun has an average daily readership of 7,700,000, the Daily Star has 1,500,000, the News of the World has an average Sunday readership of 8,200,000. So each week millions and millions of readers are exposed to Page 3.
In addition millions of people see glimpses of bare breasts on the top shelves and news agents and on telly after the watershed.
There really is no excuse for asking mothers to hide breastfeeding.
