I've always had a close and loving relationship with my dad, we have a large family and he's been an amazing hands-on father and especially grandfather to his 12 grandchildren. He's provided some childcare since the eldest grandchildren were born (my brother's children) and still does for all the latest grandchildren. He and my mum have my children once a week, and they provide school holiday cover etc. They are absolutely amazing.
I've noticed lately my dad has started to lose his temper with the kids and snaps at them grumpily. It's so out of character. My mum possibly notices as she steps in and brightly/loudly removes child with soothing words. It's over the usual things we all get frustrated at - slow putting on shoes, leaving plates around or moaning about what's for dinner, that sort of thing. But he's always had the patience of a saint and totally indulged them until now.
He's also made some weird decision. Small, but weird. He let my son (7) watch a complete inappropriate adult true crime show. He knew what it was as apparently he's watched it too. It's so unlike him.
He took them an hour's drive to a safari park and decided when they got there that weren't going in after all and they should all come home. They had even taken a picnic with them and my 4 year old was absolutely distraught as she'd looked forward to it all week.
I'm not sure whether to raise anything with him, or how? We get along well but I don't think I've ever had a conversation like that with him. Not sure where to start. Or do I just leave it? Maybe it's a blip, or maybe I'm over reacting...
