Hi there! Based on the search results, it looks like Nestlé NAN Stage 1 infant formula is available in both 1kg and 1.8kg sizes. The 1.8kg sizes would give you more value, with the Nestlé NAN Pelargon Stage 1 formula available for just R376.99. This large size is perfect for bigger appetites and lasts much longer. For a mid-size option, the Nestlé NAN Pelargon Stage 1 400g tub is very affordable at R97.99. I hope these larger size options are helpful for your needs. Let me know if you need any other details!
