It'll be way too late now, but I agree with Miss Merlot about the control being yours. Thankfully I've not had full blown tantrums to deal with since my kids were toddlers, but I seem to remember it was best to just let them get on with it. Of course, the frustrations of toddlers don't have the heartbreaking losses of dementia at their base, so I'm not saying they're directly comparable or anything demeaning like that. What I am thinking is that they're storms you can't stop, so exhausting as it is and as long as you're confident your Mum's safe, it might be better to remove yourself until the storm's blown itself out. Hope that's happened and your nerves aren't too, too frayed, Toni x
