Koko Yoghurt

Does anyone know where to find KoKo plain yoghurt in west London? It’s been recommended by the dietitian due to the added calcium as my baby has cmpa amongst other allergies. So far I have looked in: Waitrose - Shepherd’s Bush Waitrose - Kensington High Street Waitrose - Notting Hill Tesco - Brook Green Tesco - Earls Court Tesco - Notting Hill Tesco - Holland Park Whole Foods - Kensington High Street Some of them have the raspberry flavour of this brand but this has too much sugar for babies!
