Let's talk generations, my parents had children 50s/60s my mum was sahm because that's how it was, no mortgage no expensive cars, wide-screen tvs , no holidays, we had the bear minium, she looked after the home and children dad went to work,
Next generation, me, mortgage, holidays, both working full time, I had no grandparent support so I worked nights while h worked days, we managed
My point is, that I do think there is an expectation for grandparents to step up or in as this generation has the big mortgages big careers, so yes I get it when nursery fees are what they are along with after school programs,
My daughter became quiet poorly after second child, lost her driving licence, unable to work so yes I helped out alot, I was working full time too, of course wouldn't have had it any other way,
Op has seen many of her friends step in and quiet rightly is thinking about her future as she said she has plans, and that's great, I have said before, do as much as you want like, support children were you can , but it's OK not to be so involved too, I had no choice but that's life, if we could all be sahm we wouldn't be having this conversation now,
Op was asking , never is she expecting her children to support look her in later life it's not tit for tat,
