how did you know when you were done having kids?

I have one and like the idea of only having one but I worry he will want a sibling when he's older. And I worry I'll look back and regret not having another but in the present one is so much easier and better in my opinion.. I think about things like Christmas and holidays though and think I may regret not having more.
