He’s had two big birthday parties - one when he turned 4 and one when he turned 5.
When he turned 4 we had a bouncy castle in a hall party and invited all his nursery friends plus a few from outside school. When he turned 5 last year we invited all his reception class, that was a soft play one.
I said next year he can choose a few friends to go bowling or something, but this year we’re just having a meal with family.
