I think it depends on the age of the children of those whom you are asking.
When they are adorable newborn babies and everyone is interested in you, your health, their milestones and the baby smiles and adores you - yes, it's worth it.
When they are toddlers to about nine, you can't turn your back or sit down or watch TV or have an unbroken night and you fear your brain has turned to Minecraft mush - maybe not.
When they are nine to teenage, thoughtful and good to chat to, you have a little more freedom and they are mostly still biddable and think you are god - it's great again.
When they are teenagers to early twenties, think they know it all and rule the roost, you are inconvenient hangers-on who stop them having fun and they keep you up all night either waiting for them to ring and need a lift, waiting for them to get home safely, or just banging and crashing in the kitchen making toasted sandwiches at three a m - yeah, no.
When they are adult and have left home and you go round and visit their lovely houses and they buy you wonderful thoughtful presents and help you move that heavy furniture and cut the lawn - best thing in the world!
So, yeah. Depends.
