Finished having babies

How do you know if your finished having babies? I’m in two minds, I think my partner is too. One minute I want one next I’m like nope, I’m done, want some life back; go back to work, no sleepless night I’m done, but then think about small little baby again. I do like the idea of having 3 children as I got 2 boys at the moment aged 2 & 6. Having a third though also does mean moving house as I’m in a 2 bed property at the moment so would be a squeeze.
