Re: Brain Damaged from too much shaking?
Yes, very sad.
Child protective services (CPS) should be called and everything you know reported.
You can do the reporting anonymously, but have all of your facts ready. Be prepared to give information such as the address where the children live, where your sister and her boyfriend work, and specific instances you witnessed of abuse, including the days and times. It's too bad things weren't better documented and CPS wasn't called back when this child was a baby, but you can still call now. For the children's sake, "writing them off" is not the answer. Contacting CPS is important, so they can investigate.
