Is it bad to change jobs quickly?

Personally, I always kind of had that feeling like, 'If I move a company, I don't want to leave too early because it would look bad on my CV. Why would I leave a company after a few months?' But if another company kind of reached out to me, even though they know I haven't been that long at my previous company, then why not? And at this point, I'm at my new company, I'm quite happy here. And I feel I would stay here for a bit longer. So that will kind of, I think, cover for the previous one.
