how to style fist child in React Native-CodePudding

I need to apply marginLeft:4 to all elements except firs one for styles.option , how can i get to style only the first child in React Native? Is it possible not installing any new packages to the project?

 return (
        <View style={style}>
            <View style={styles.container}>
                {options.map((option) => (
                    <Option
                        checked={option.value === value}
                        key={option.value}
                        label={option.label}
                    />
                ))}
            </View>
        </View>
    );
}

function Option(){
  return (
        <Pressable
            style={[styles.option, checked && styles.checked]}
        >
            <Text>
                {label}
            </Text>
        </Pressable>
    );
}

const styles = StyleSheet.create({
    container: {
        padding: 4,
    },
    option: {
        marginLeft: 4,  //Need to apply this style to all elements except firs one
    },
    "option:first-child": {
        marginLeft: 0, //This does not work
    },
