Honestly I cannot say I am intending on using these as I only got them as a back up in case things go wrong at home and I cannot breastfeed. However, they are pretty much the only NZ formula brand I would consider giving my child looking at the ingredients and how it is made. Love the fact that I can get sachets and not just the can, and the packaging is absolutely adorable. The thing that impressed me most was that the order was shipped with post haste and we got it within a day or two, which meant that every order is a priority and that is how you know this brand actually cares about their customers. Yet to use the product, but already impressed.
