Soy milk in Singapore

My girl have been taking isomil soy. However not sure for what every reasons, suddenly we couldn't find isomil formula for 1 year old onwards at fair price and even jin tai Mart. So currently we are giving her nutrisoy UHT but the smallest they have is 250ml which she would not finish some time and her school does not have a fridge to keep the balance. So is there any other brand to recommend?
