Breast milk varies from day to day (and hour to hour), so you may find that expressed breast milk has a different colour, volume, and consistency – it is constantly changing. For this reason, convenience and nutritional value are critical to our customers. We combine all of your breast milk before freeze-drying, so your baby receives a broad spectrum of nutrients from your entire breastfeeding experience in each and every bag. It’s like a powerhouse of nutrients in each bag! You only get the ONE water ratio for each bag, so you can decide how much or little you need for your baby.
