I haven't tried bubble no, blackfriars, I will PM you now thank you :)
Paranoid schizophrenia is an unpredictable illness. You being the subject of her paranoia would make me think she’s becoming possessive over your mum (her sister) and in her confused state sees you as a threat, which is very worrying
Yes that is exactly what I'm worried about. She is extremely possessive over my mum and it's clear she sees me as a threat to her time with her.
Your mum has her hands full looking after her unwell sister. I think it’s unreasonable to say she should leave her sister alone (un-medicated and paranoid) while she babysits for you. She’ll be worrying about her sister all day and what does she do if her sister turns up at the house in distress? Turn her away? Wouldn’t that add to your aunt’s paranoia?
I can understand where you're coming from. The thing is, mum wasn't worried. She probably should have been but she wasn't. Until now. She's that used to her sister saying weird things she doesn't think much of it when she comes out with things about the royal family, phones being tracked etc. which she has been saying in mum's company (just not the other stuff about me)
My aunt actually had plans to go and visit a friend today, which I didn't know about, and she went off to see her as planned. Mum came round on her own and I spoke to her in-depth about what aunt was saying.
She said she had been coming out with some bizarre things which is not unheard of for her but didn't know about the things I mentioned on this thread, she also said she has been taking her meds as she's seen her taking them 
She said when she was at her place last night she was shouting out in the night though and made her jump.
I don't see how she can be taking her medication as prescribed and still be having the delusions that she's having, that wouldn't happen would it? So she can't be taking them, at least not as prescribed.
Anyway, mum wants to report it to the CMHT on the basis that she's been saying things about me/mum personally and it has unnerved me. I don't know what they'll be able to do about it but it's being called in tomorrow morning.
She still wants to have the children for me and suggested saying that the date has been changed, as pp suggested, but I just don't think it's going to work.
I have to be at the hospital at 7am as I'm scheduled for morning surgery but I can't guarantee what time it'll be. The chances are it'll be early, before noon, unless emergencies come in - but then there's always the chance it'll be pushed back until the afternoon and she would need to be sat at my house half the day.
Do you have a friend who could come to the hospital with you for moral support? Or a friend who could look after your kids for the day if your DH is determined to attend the birth?
Unfortunately not, mum is all I have locally.
