Why? Do they cost more per baby just because they're a multiple? Genuine question as that makes zero sense to me!
I have twins (in England) and yes it's often more expensive to have multiples.
There are no hand-me-downs from older siblings for a start, so you have to buy two rear facing car seats (for example), you have to buy a double pram (more expensive than a single), you have to buy two cots/cot beds/bassinets.
If you're using bouncers, high chairs, cutlery crockery etc there is no reusing from older siblings so everything has to be bought in multiples (or of your are reusing from a sibling you still have to buy an extra set or two).
Multiples are much more likely to be premature (full term for twins is 37 weeks and any baby born earlier than 37 weeks is premature), I'm sure full term for triplets is something like 32 or 35 weeks. Earlier births with multiple children means it's much more likely that you'll need to use formula in some way as a parent to multiples, which is obviously expensive.
Also the rate of divorce of parents of multiples is higher than that of Singleton parents (according to Twins Trust)....so perhaps this is one way to help alleviate some of that financial burden and try and help families have one less point of angst.
When your children start nursery often parents will plan kids to have a new baby start nursery at the point the oldest goes to school so you only have one child in nursery.....you don't have that choice with multiples. So although the cost is the same over the lifetime, the cost comes all at once which is unaffordable to many.
I could go on. 😊
