As a former foster mother, I have experience with the system. Someone said that unless the kids are injured to the point of hospitalization, there is little to be done. To some extent that is true. I would suggest not calling just once, but to call 1-800-4ACHILD several times, maybe a day or two apart, giving more info each time. One call about the older child not eating for days, another about him being thrown into the wall, another about drugs, another about him being a babysitter. You can remain anonymous. The more calls they get, the more likely there will be a very serious response. Over one call, they are supposed to go to the house and talk to the kids separate from the parents, but if he won't tell them, they go on their merry way. Another call will ensure another visit, and another, etc. They will ask you times of occurrences, if you have personally seen any of this or if the child told you this directly, or if you were in the room when he did, so be prepared. I have made reports to this hotline and no one found out it was me. In fact, in one case, I told the mother I did it, and she didn't beleive me!!
Please call ASAP. You would feel so guilty if anything happened to those kids.
