Always wash your hands carefully before preparing the bottle. Wash and sterilize the bottle, teat and all utensils to be used. Boil drinking water for 5 minutes and let it cool to 40°C or heat bottled mineral water with a low mineral content to 40°C. First, pour the necessary amount of boiled water into the bottle. Using only the measuring spoon included in the can, add the correct number of spoons of powder, smoothing the spoon with a clean, dry knife; do not settle the powder. Cover the bottle using the rigid plastic cap, shake well until all the powder is completely dissolved and free of lumps. Remove the cap and place a sterile teat in the bottle. Allow to cool to lukewarm temperature (37ºC). Test the temperature by pouring a few drops onto your wrist. Immediately give the prepared bottle to your baby. Do not store leftovers in the bottle, throw away the amount of milk that is left over.
