I remember reading in a Nigella cookbook of all places, her commenting that (I'm paraphrasing from memory) something along the lines of her being sandwiched between looking after children, then looking after parents and "her time" never seeming to materialise.
This was years ago (I think it was in her book Feast) and it really resonated that could be my fate.
I think it's partly because we are generally having children in our 30's rather than twenties, so we end up with more potential crossover between parenting and looking after ailing parents.
That said, I think there is a much higher expectation of what parenting is today and it generally seems (as with care of elderly parents) to fall to women to do the lion's share.
I think my parents were good, but looking back they didn't have to do half as much parenting as I have. Things like after school activities for example. Or playing taxi (I remember regularly cycling 5 miles to my friends house and them also in return) but there is no way I would let my child do that at the age I did (from about 12). The traffic no is so much worse than it was.
I've definitely done my best to teach independence skills - such as cooking/laundry/housekeeping etc and that's fine and
not an issue now as young adults.
However I definitely notice a lack of resilience/self reliance compared to myself at the same age - some of which I find odd when so much information is available on the internet to solve issues that I never had (such as bus times, how to fix a bike puncture etc).
I'm not "done" but I am making a conscious to step back and let them "fail" post 18 years old.
I have come to think that not allowing them to "fall" sometimes means they never learn how to pick themselves up or even realise they can and better, to learn from those experiences.
