AIBU to ask what is a normal amount

[fourseatsandasteeringwheel]

DH's parents are divorced. My DM is a widow (not a recent thing). Of them all, I would say FIL has the 'worst' social life and DM has the most active.

DM routinely will get annoyed that we don't see her often enough. We see her once a week for a meal and possibly will see her when dropping off/collecting DC if she babysits (perhaps once a month).

We see MIL once a week also when she has had DC and once a month just because. FIL is more as and when as he still works.

We both work full time, DH is also doing an OU qualification and have 2 DC who have activities through the week and at the weekend. We probably have about half of Saturday and half of Sunday not allocated to DC activities.

In addition to seeing DM and PIL separately, DH's grandfather is housebound so we try and visit him at least once per fortnight. We also try and see my nan once a month minimum.

Are we being unfair not seeing her more often? Is this amount considerably less than normal?

I see my parents once every 2months or so? Maybe less? We all live jn the same town.

My partner sees his maybe slightly more, they live about an hour away and he pops over when they fancy it - I dont tend to go. No reason, I love them a lot, but there's always something happening or to do atm.

We both work, as does my mother. My dad and stepmother are too busy travelling and having fun to worry about seeing us, and his parents are pretty low key (although would probably like to see partner more, but understand he has a demanding job and likes to chill).

So obviously, to me, you're seeing her quite a lot.

It varies so much. Some people see their parents every day, others see them once every couple of years or not at all.
Once a week seems fine to me.
