aussienic - whislt i get what you are saying, it bears remembering that you are intelligent, educated and aware. Possibly even well supported in your parenting.
Not all parents are. Some are heavily influenced by these ads, and they truly mean to do what is best for their child, and they see this as a way of doing that.
Sometimes we all need to stand up for these mums and dads who are lacking the quality of support and awareness that we have.
