Thanks K, S12 is doing better. My girls got it late in the week but they are on the upswing.
D9 started coming down with it on Wednesday so my wife brought the kids to my house because she knew my Mom could stay with D9 during the day on thursday. I assumed it was so she could go out but when she came over she said she was tired and was going to go to bed when she got back home. I told her that she always looks tired when I see her and she says that she's always tired on Wednesdays because she goes out Tuesday nights. Of course she said this with a sheepish look on her face like she was embarrassed by it.
I texted her on thursday to let her know how the girls were doing and she responded by saying that she wish she could take care of them and she felt as if she was failing. From bits of info she's given me during conversation, it seems as though she spends a lot of time alone at home.
