I would have loved 4, but 2 is my limit - I have twins and it wasn’t financially viable for me to work (as a family pot, we’d have been ££££ out of pocket) so I became a sahm.
To persuade me to have more kids:
Heavily subsidised or free childcare for 1+ year olds going up until my child is old enough to be left at home independently.
The removal of the child cap on UC. I don’t want to have a relationship break down and a brood of children that I can’t support on one wage. I don’t claim UC, but life can change in an instant.
A proper child support system that forces the NRP to actually pay for their child(ren) rather than the shit show we have now.
Subsidised quality housing for larger families, kids and houses are expensive and if they’re trying to encourage us to have more kids, they’ve got to be housed. Otherwise the take up would only be the higher earners, and there’s more lower or normal earners I think.
Better NHS care, MH provision, and children services provision. My DS has speech issues, we’ve waited over a year to see an ENT, SLT have disappeared, and he has additional behavioural needs which he’s also waiting on. He’s a very mild case, but parents don’t need to have to fight tooth and nail for every scrap they can get (especially if they’ve had a large family) because that’s a full time job in itself and they still need to work to provide for said kids.
Basically, I think if the Govt want us to produce more children, it needs to be massively subsidised and financially viable regardless of personal income. No idea of how the country would pay for it, but these are the sort of things that would make me consider more children - a piece of paper from the Queen would not cut it I’m afraid!
