I don't know if it's regional or not, but I have friends who see their parents several times a week with their kids.
Nope, not regional. Some people 55+, just like a quiet life, and have earned their stripes looking after and raising children, and some people genuinely get weary and tired easily when they're 55+ - especially around boisterous high-energy children! And they can't be doing with entertaining their adult offpring's children because their adult offspring can't be arsed to do it themselves.
Also (shockingly!) some people have no desire to spend 3 days a week with their grandchildren. Some of us have hobbies, friends, and jobs, and a social life. And also like to travel. Me and DH don't have grandkids yet, but I think we would find our adult children coming around 3 times a week with their children, (and staying for hours,) as many people YOU know do, very restrictive and tiring.
I have seen too many cases now of young-ish adults just turning up at nan and grandad's house to offload the kids, and share the load with their parents (the kids grandparents,) because they can't be arsed to entertain them themselves. 'Oooooh, Conor and Chloe wanted to come visit nan and grandads didn't you Conor and Chloe?'
Yeah right, more like mum and dad wanted to come to share the boisterous-children load! Fine if that's the reason, but at least own it! And FFS cut your parents some slack if they want some peace and quiet and don't want your noisy and boisterous kids around all the time
