Even though there are a great many recommendations on ways to provide optimal health benefits to babies and children, none are official laws except using proper car seats. Every parent does have the right to make decisions regarding their child's medical treatment without fearing someone will turn them into child protective services simply because they choose to parent in a way that is different. Her level of education doesn't necessarily make her ignorant. I know some very good parents who never graduated high school as well as some pretty horrible parents with doctorate degrees. It is not at all unusual for parents to be reluctant about giving vaccinations. Yes, it is recommended, but it is not required for entry into school. There are parents who won't vaccinate due to personal or religious beliefs as well as children who aren't able to be vaccinated due to health issues. It is simple enough to sign a waiver for admission to school. Her arguments about deaths from vaccines as well as autism are common concerns for parents who choose not to vaccinate. It is true that it is recommended for babies under 12 months to receive breast milk or formula, but there is no law requiring it. In years past early introduction to whole cow's milk was not unusual and some people are firmly anchored in doing the same things their parents did. There are things that parents in years past regularly did such as place babies to sleep on tummies, not use car seats, give baby aspirin for fevers, and feed with cow's milk. Studies and research have shown these are not the optimal ways to keep a baby safe and healthy. Even though I vaccinated my children, I support a person's desire to either delay or not give vaccines if that is what they feel is right for their children. I agree that her under 12 month old baby should be having formula or breast milk, but the cow's milk isn't going to kill the baby. Personally, I feel that unless your friend asks for your opinion and advice that this really isn't your business. Her children are not being abused and they are not being neglected. If it bothers you that much than it's best to end your relationship as she won't likely change her preferred way of parenting and you'll always be agitated at her choices.
