So I took some advice I was given here and sent a email to the social worker (because she is hard to reach via phone - go figure) and indicated that not only is it illegal but the BM would have no way of knowing what medications we had already given SD9 therefore she could have double dosed her or the drug could have had an interaction. We also indicated that is would irresponsible for us to give her medication that was not prescribed by a doctor to her and perhaps the person supervising the visits should pay closer attention to what goes on.

I shudder to think what will happen when she starts to get un supervised visitation...

Thanks everyone!
