Thanks for the replies so far. Today it seems that MIL has improved. I don't think she will last much longer but it no longer seems her death is imminent. On the other hand I heard from my brother today and he has taken a major turn for the worse. DH and I decided that we will tell DD and take her to see him in about 3 weeks. It will be after school starts for both of them but we don't think we can risk being so far away while his mother's status is still questionable. We had a vacation planned for next week that we think we will cancel and spend in the area closer to his parents instead. This means we can visit MIL and FIL and also be nearby if things go south.

Bad, bad timing these things have...
