I think it depends on your lifestyle?
There are loads of low income households with multiple children. They manage but their priorities may be different to a high incomes household with 1 child.
Im currently pregnant with second baby (woohoo!). I’m super excited. We’re probably classed as middle income for where we live (north).
we’re not worried about finances.
But we have a lot of family support so don’t have to pay for childcare. We also live in a 3 bed terrace rather than a semi, so a small mortgage. We have 2 old cars bought in cash rather than finance so no car payments.
We can probably afford 1 foreign holiday and 1 long weekend away a year with 2 kids.
we probably won’t be paying for uni fees or whatever but that would be the same for 1 child. Depends on our circumstances at the time. I wouldn’t base my family planning around it. Neither of us had it paid for us and it was fine.
Rather than gifting a house deposit we’ll let kids live at home rent free to save for one. Would be the same if we stuck with 1 unless we came into big money.
We will pay for driving lessons as that’s an essential for expanding life opportunities. But they won’t be able to do lessons at the same time anyway as 20 months apart, so not x2. More like a long drawn out x1.
Kids have saving accounts for birthday/Christmas money and also we put in a couple of quid every month. It’s not a priority saving but more a ‘nice to have’. So they’ll each have a few grand each by the time they’re adults. It’ll be nothing like a house deposit but a nice small nest egg.
However another household would find saving a house deposit for their kids an essential or covering university fees, private education etc. So they’d only have as many kids as they could pay a house deposit for.
I also choose to work 3 days a week and have family for childcare. So doesn’t impact 1/2 kids.
Another family may both work 5 days a week and use nursery. So finances would massively differ from 1-2.
