Thanks all! We got her into the home around the corner from my MiL. I'm just busy making food now but will pop back in later (starving).
Basically it went ok. Social workers agreed with me- couldn't not really and approved funding this am, so we took her along this afternoon. After a coffee there got her settled and then eventually thought it was time to leave. MiL went first and waited outside for me while I told her she was staying there for a week (technically that's alls agreed anyway at this stage). She seemed confused nut open to the idea of a little "holliday" so didn't go half as badly as I was anticipating. Then again I'm becoming an expert at breaking bad news! I'm sure she'll be fine in a few days. Best part is my MiL feels so relieved that nanna is safe.
Oooo think I smell burning- will be back later!!!!!!
