My friends had to stop Daddy doing the bedtime routine too Tee.
Their eldest would just go hyper-hyper and wouldn't settle. Seemed obvious in hindsight, that he'd come in from work half an hour before bed, so to their DS that was his time with Daddy and it was play time.
I felt really sorry for my friend, he loves reading the bedtime story to his son but now he reads downstairs and Mummy has to do the bedtime routine afterwards.
How are the rest of the Puddlers today?
All ok here, things have improved after a few rule/routine changes. Part of me is also thinking that hormones may have been at play - purely for the sheer unreasonalbe and out of character behaviour of DD. She is now almost pleasant 
I go to see the Neuro Dr's on Monday, to discuss my wish for a natural birth over a c-section and how feasible that is with my medical history. Not sure if they are going to give me their opinion on the day or write to my Consultant with their advice/opinion first.
Am going to see my nan tomorrow, don't want to (god that sounds awful - I don't mean it horribly) I just dread what she will be like and my mum has said if she asks then I am to tell her exactly what has happened. I doubt she'd take it in and what exactly am I to say "your dementia has caused this, hope you are pleased with yourself?" 
So I think I will circumnavigate the subject. I am going for my mum, as i know she is wracked with guilt but she really is too unwell to visit her and risk having more stress piled on her shoulders 
I just keep thinking that the nan who was there before the dementia took hold, is the reason why I will not stop seeing the nan we have now. 'Normal' nan would nver have turned her back on any of us in our time of need. So as hard as it is, as unpleasant as it is, I will go and visit. Mum will too - once she is recovered and not at risk of a heart attack just from stepping into the house!
