Kids can jog by randyxx at Mod The Sims 4

Send your played child sim jogging.
Now just like the teens and adult’s your child can go jogging.

When playing a child sim, click on that sim
Next stroll through menu and click on ” GO JOGGING”

Your sim will change into their athletic wear and jog a short distance.
Your sim usually returns to the same area they started in, but I have had some decide to stay in other areas.

This mod adds child sims into existing Sims 4 base game XML tuning files and may conflict with other mods, that mods the jogging files.
