Well with mine, then 8 and 6 (girls).
We fired up Harmy’s ANH and watched it. It actually took a few days, as we would stop and talk about what was going on. They didn’t seem to react harshly to any of the violence/gore.
Then we went on to ESB and ROTJ DeS. Followed the same flow.
After that we watched AOTC and ROTS, then saw TFA in the theaters together, and have since saw R1.
