C.G.
I think what I would do is take my child out if I had concerns about the care my child is getting, but at the same time I would try to help this lady if I could in other ways.
(You shouldn't feel bad for doing something you feel is best for your daughter. )
I would definitely try my best to help this lady through some of her rough times, if I had the resources to do so, and it dosen't have to be $$$$$$$-- I don't know her whole story and everything she's going through but I bet you could help her in other ways.
Good luck.
