Lots of stuff gets dodgy marketing. But this isn't just a new shirt or a car... it's our children's health and wellbeing.
parents should have access to full information about what is actually in these products - current advertising does not provide this information, however. What it does is sell misinformation to parents, many of whom are quite vulnerable to messages about better sleep, greater contentment, better health, freedom from the demands of breastfeeding and so on.
These companies do not have an interest in the long-term wellbeing of babies. So long as there is no immediate and demonstrable harm, they're fine and they can sell their stuff - whether it be formula, baby food or whatever.
The way they market these products DOES matter. It should matter most of all to parents using these products. There isn't a lot of information around - marketing doesn't help with that though.
Do we really know what's in the products we feed our kids? It's an important question with life-long ramifications. Once again, advertising does not address wthi issue, it hides it. And advertisers know that the surest way to muddy the issue is to try and suggest that formula-feeding mothers are somehow being shamed for using these products. They know some mothers feel this way and they use it - if you get angry at anyone questioning their products or their marketing, then you're not questioning them yourselves.
