I don't have a problem with anyone advertising extended BF or Toddler milk so long as it is ethical without the guilt trips and misleading information.

I think the formula companies just have this constant advertising push because they know that they only have x amount of years to get parents to buy their products before their children are too old to have it and are on either regular cows/soy milk etc. Because regardless of how you fed your child, there comes the time when they are too old for both BM and formula IYKWIM? Even if you only ever buy one tin, they have made their money.
