We have three part sets. We are childfree, but both perfectly capable of dropping the odd bit of crockery.
Some that PILs bought us as a housewarming present for our first house, so now around 25 years old, standard high street set from somewhere like Argos or a supermarket, the odd breakage, but mostly still in existence.
Topped up by some cheapy Ikea plates, not many of those left as they broke and chipped fairly easily, but the ones that are left are probably around 15 years old.
And then 2/3 years ago, I bought my first grown up Denby plates in a Black Friday half price offer, but still bloody expensive. I'm in two minds about whether they were worth the extra cost as they take up too much room in the dishwasher due to the shape and they look a bit tatty scratchy TBH. In hindsight, I wish I hadn't bothered. However, they're otherwise very sturdy and as we're in our late 40s, they'll probably outlast us.
All get used routinely as we just keep using them up until the dishwasher is full.
