Safe Way To Travel

Ittravel namin yung 6 month old baby ko. Wala kaming car seat. Ndi kami bumili kc wala naman kaming car. I'm planning na ibaby wear na lang si baby. Suggestion naman kung anong safest way na ibaby wear si baby pag magttravel sa sasakyan. Facing outward ba or inward? Thank you in advance.
