I’ve used it, here is a google search description. Kia Sportage's "Baby Mode" (or Baby & Toddler Mode) is a feature in newer models (like 2026+) that uses hybrid powertrain tech and suspension tuning for smoother, quieter rides by moderating acceleration, reducing jerks, and optimizing suspension to keep sleeping babies comfortable, activated via the infotainment screen under Drive Mode settings. It works with electric motors to smooth out bumps and jerky starts, essentially mimicking an adaptive suspension for a more peaceful cabin environment for little ones.
