We were only ever going to have two children for all the reasons outlined above.
Like a PP, we thought ‘Wouldn’t it be nice to give DS1 a sibling’, and ended up with surprise twins when DS1 was 2.5.
We had to get a new car that could fit 3 car seats in a row. A massive purchase we had NOT budgeted for.
Very modest holidays that would have been within our reach financially with 2 DC were too expensive because of having to get an extra room for the third child. The rules of many holiday cottages mean you’re not allowed to squeeze a third child into a two bed place, even though they’d easily fit on an airbed or sofabed, so that pushes you into bigger properties than you can afford. So we just didn’t go on holiday!
We are able to afford a trip abroad for the first time this summer (in the nearly 7 years since the twins were born), and one of us will have to stay in a different ferry cabin with one of the children (there are only 2 berth and 4 berth cabins so we had to get two cabins) because, as others have pointed out, the cabins / rooms are not always together!
In a lot of restaurants there are often plenty of tables for 2 or 4. If there are 5 of you, you often get seated at a table for 6 and someone has to be on one side at the end, leaning round to be part of things.
Don’t even get me started on theme park rides with 3 small children. It’s like a management training exercise.
None of this is a big deal in the grand scheme of things, but our experience as an accidental family of 5 has been that generally things are set up for families of 4, and it doesn’t half wear you down after a while.
I don’t really understand your point, OP. Yes of course people can ‘just’ book an extra room or an extra ticket for something, but 9 times out of 10, doing that is disproportionately more expensive and / or faffy! And it’s ALL THE TIME.
