I posted a few weeks ago about my DD11s father suddenly becoming obsessed with the QAnon conspirancy theories, talking about God sending him messages to save the children, how Trump is saving us from the devil and Covid is a hoax etc etc. I've let him see DD once since, supervised constantly and very closely by his mum - she is completely onside and I know she wouldn't let him say or do anything weird. DD adores him so didn't want to keep them apart entirely- she has no idea whats going on - but I also believe hes having a severe mental breakdown.
He's now bombarding me with anti-vax stuff, telling me he won't consent to her having any vaccinations from now on, wants details of her school to send them letters saying they can't take her temperature or administer a covid test (not that they want to!). Hes saying he will put it on record she is not allowed a covid test in any circumstances (as they will use a fake positive result as an excuse to kidnap her and sell her to a paedophile ring). I'm worried sick, I'm going to try and contact social services tomorrow for advice and look for a good family law solicitor but I was hoping someone might know - can he do all this? He's on her BC so has parental responsibility, he sees her maybe twice a month on average now he lives nearby but has gone nearly a year at a time between visits on occasion. He hasn't been a proper part of her life since I kicked him out when she was 3 because he wouldn't stop smoking weed. Does any of that matter, or can he just roll in now and put her in danger by refusing medical treatment for her?
