Kids don’t stay small forever. As if by magic they grow up and will enjoy doing stuff and actually remember it.
Why do you need to go on a trip far away every two years - there’s seriously nowhere closer that’s worth visiting? Save up, do local vacations when the kid is small and hold off on that Australia trip 'till he old enough to tell his schoolmates about the crocodile he got to ride.
You’ll all remember it.
Same goes for restaurants. Some are child friendly and some aren’t. If I’ve saved up to go to a Michelin restaurant and gotten a sitter for my kids (who don’t enjoy the food and can’t be expected to do something as dull for so long) then I don’t feel happy that the couple at the next table brought their noisy offspring - either they have money to waste and don’t care about eating hot food, or they ignore their kid trying their damndest to eat. Which ruins it for everybody else including the kid.
But of course as a considerate parent there’s plenty of restaurants where you can go.
And no, we didn’t get to see many movies in the cinema when our kids were small. We had the same system Roger describes - which I did once and my wife several times. Here everybody else is a parent too and of course expects disturbances.
