Be very careful and avoid any talks alone between the case worker and your children. They do not have to talk to them alone, even though they will tell you different. If you allow it they can say the children told them that you beat them daily and it would be their word against yours. Even with no physical evidence it can give them a cause to stay involved with your life and take the children and force them to see a medical. And if you do not vaccinate that can be a whole different issue as they would be vaccinated as soon as they see the doctor CPS takes them to which is usually just the health department. And all that because they lied to take the kids. Than you would have to fight in court to get them back.
