How often do you clip your cats nails?

I currently have 4 exclusively indoor cats. I’ve actually owned cats for many years. I’ve never really paid much attention to how often I trimmed their nails, just did it whenever I noticed they needed to be done. But now I have a human baby and I feel like I’m not paying as close attention to my cats as I did pre-baby (not to say they’re in any way neglected just that my focus is more split now) and I feel like it would be best to get on a schedule.
