I think the ‘tit for tat’ attitude that if you don’t provide childcare on tap, then why should your kids care for you in your old age, really stinks. Sad that some people view relationships as a series of transactions
It’s entirely reasonable to not provide free care (it’s a massive commitment) and it would be utterly selfish for an adult child to ‘punish’ the grandparent for not doing it. There’s no automatic entitlement, just as there’s no automatic right to be gifted House deposits
Having said that, dh and I would happily help out (provided we are retired) not because we feel we should but because we’d want to. Oh and providing it’s what our children want. You do read some threads here where grandparents are foisting themselves as childcarers when the parents feel the children would benefit more from nursery
And btw those of us in the age bracket to be grandparents, didn’t all have it so easy... we didn’t receive any help from our own parents, and yes, house prices were lower but mortgage payments in real terms weren’t - those of us who lived through the era of interest rate hikes had a precarious time of it, and even when rates were more stable they were massively higher than today. Also childcare wasn’t subsidised by free hours, and for many of us lasted much longer because we were back at work after 12 week maternity leave. So it’s swings and roundabouts really- yes it’s tough in some ways for the younger generation, but if my adult dd decide to have kids, they’ll be able to have 9 months or even a year off work, their partner will be able to have some time off (even just the two week paternity leave is two weeks longer than my dh had) and their children would be entitled to an amount of free childcare from age 2 or 3
So I wouldn’t see dh and I offering help as a kind of ‘duty’ to pay back because we had it easy - we didn’t! We would offer support because we want to. Neither would we see it as a transaction which then entitles us to old age care
