Both sets of grandparents have always said they would not do regular childcare. Happy to see them with us and my parents usually have them for a couple of nights in school holidays. MIL doesn't have them without us and all this is fine.
We have two older children in teen years and a one year old. As I said parents didn't do regular childcare for my children and I used nursery. They didn't do childcare for my brothers children either.
However when my sister went back to work after her daughter was born my parents looked after her 5 days a week and often overnight or weekends.
Was, quite pissed off but didn't raise it as ultimately it's up to my parents. My husband was more annoyed as his mum "would never do that for one and not the other." He was always nagging me to talk to my dad (it was, really him that wanted to look after my DN).
Now MIL is looking after SILs kids in the holidays. She never did it for our kids.
I feel like my older children must be awful children for their grandparents to treat them so differently and they have noticed the difference and frequently say their grandparents don't like them as much as x, y or z.. Or perhaps we are bad parents or our parents don't like us much.
I think this has been triggered by paying for childcare for our son while other family members get free childcare (when they have more money too).
I don't expect anyone to look after my son. I understand a baby is more work than 4 to 8 year olds (nephew and nieces are between these ages) but they didn't look after my older children when they were these ages either.
I know grandparents can do as they pleased but surely it's wrong to offer free childcare for one but not the other? Or maybe not. They can spend their retirement how they want
What do you think, is it reasonable to offer childcare to some grandchildren and not others?
