Small team

If you have a small team under 5 people, do you do 1 on 1s? It seems almost silly when we talk every day and I checkin every week informally, but I keep feeling like I should once a month. Any advice on small teams appreciated thanks!

Edit: not sure why downvoted I know 1 on 1 is important, not saying it isn’t. To clarify, we talk about goals, coaching, etc in checkins, so do i need 1 on 1s if it’s covered already? We generally don’t have issues and they have no promotion goals.
