Taking picture of foster kids?

I don't email or share pictures online of the kids. On facebook I said "foster daughter" but now I just say "my four year old" or "my son". I did text a picture to my sister's phone of the kids. And the other day the kids were all on tv because we were filmed at a family fun night at the school. I did not know that they were being filmed and would bebe on tv so hopefully that doesn't get me in trouble.
