MIL has been in hospital for 4 weeks and we have just been told they suspect she has Alzheimers and cognitive impairment, she is very agitated, has obsessive behaviours, hallucinations and confusion and recently had a seizure. The children have not been to see her as DH felt the ward she is on is not a suitable place for them. She is coming out next week but we are not sure how she will be and if she can stay home, depends on how FIL copes. DH is obviously upset, me not so as we have always had a bit of a difficult relationship. DCs are 9 and 11 and they know nanny is unwell but not details. FIL was upset tonight and has been over for tea each night, quite down each time,DD1 had a big tantrum tonight and goes on about why we are here as we are all going to die anyway. I said to DH that we need to tell them what is happening as I think they suspect something is wrong and we are maybe holding back from them. Has anyone else experienced this situation as I would really appreciate some advice how to explain this to them without scaring them. Sorry it's long.
