Unfortunately it's life. My mum lives in the next village (few minutes away) and my ILs live one street away. We get virtually no help. Never have any of them taken any of our three children to the park in the 14 years we've been parents. My own mum has been around for a meal once. Christmas Day last year. She has never popped round for a brew or to see the kids. Neither have the ILs.
My dad, who lived 200 miles away saw my kids more as he'd come for a weekend 3 or 4 times a year, just to see them.
When we do get parental "help", it's organised well in advance, MUST be for a good reason (dinners and dates don't count), and we must be back once we have completed whatever task we need babysitters for (ie. we have to set off home immediately after whatever wedding we have been to, no time to relax with a nice breakfast the morning after). We have to be up early and heading straight home which means one of us cannot even drink at the wedding as we can't be over the limit in the morning. (Scotland law)
Once we asked the ILs to babysit while DH and I had our first and only ever celebration for one of our wedding anniversaries. The calls were coming in before we had finished our food (7pm) to ask what time we were thinking of being back. The kids are fantastic by the way, very self sufficient, well mannered and well behaved and plenty old enough to be up beyond 9pm. It's just that ILs didn't want to do it. That's all. We never asked again because it was an awful, stressful, rushed night.
My mum did the bare minimum when I was a kid and does the same as a grandma. I never got new clothes, just wore things friends gave me or, for example, made do with a jumper and joggers an aunt bought me two years previously for Christmas that were too small. Then there were only meals mums boyfriend liked (for example, if DSis and I hated fish but he liked it so we'd have to sit and stare at fish dinners we couldn't eat and go hungry) and when he was working away, if mum wasn't hungry, we didn't eat at all.
At least my future won't involve being my mum's carer 🤷🏻♀️
I understand how you feel OP, I see my friends having whole weekends away every other week as the kids are all at granny's. I see grandparents picking the kids up from school. I see friends tagging themselves at restaurants or at pubs and I wonder, why not me? But it's life. We all don't have the same opportunities or advantages others get. I'll never inherit from my parents, whereas friends will have a couple of houses each.
At least your parenting will be your own accomplishment I guess?
