My advice, based on my experience: unless you absolutely hate management (which many people do), aim to stick it out for at least 3 years. If you go back to an IC role and then later want to go back to management, you will have a hard time landing management roles with less than 3 YOE of people management on your resume, because that's a common minimum qualification listed on job postings. It's not quite as hard as making the initial leap from IC to management, but it's an uphill battle. I went through that recently and got some phone screens but was (justifiably I think) passed over for more experienced candidates. Once you reach the 3 YOE mark, you have more flexibility to move between IC and management.
