Why do competitions assume people only have two dc?

[EachandEveryone]

Every time. I was just looking at the holiday one on here. What do you do, leave one behind? Hope they will negotiate to allow one to be paid for? In rl i hardly know anyone with two dc!

Because they are promotional tools, not gifts.

IRL most people I know have one child. Only 3 families with 3+ children.

Don't enter the competition, I imagine.

Sometimes you can offer to pay for a third to be added

I'm sure you will be able to upgrade or otherwise amend the prize should you win but they have to define the prize somehow.

According to the ONS, 85% of families have one or 2 DC, and only 15% have 3 or more:

If you 'hardly know anyone with 2 DC' then the type of people you know, are not typical of the UK population overall.
