Hello, does anyone have experience driving in South Africa with children? I wonder if children 1.3 meters tall need booster seats in South Africa. Thank you all ?

I checked before, children under 1.45 meters or under 36 kg in South Africa need to use booster seats. I also asked the car rental company. The charge for renting a booster seat in South Africa is about 530 rand per rental period (I have two orders, two car rental companies, the rental periods are 4 days and 10 days, and the prices are the same, which proves that it is not charged by the day...)
