Feeding your baby

Wash and sterilize the bottle-feeding utensils*1. Cover the utensils with enough water and bring to a boil, then boil for five to ten minutes. (Nipple for three minutes)

*You can also use a microwave or chemicals for sterilization.

Slide the cubes vertically into the bottle. One cube for 40 ml of milk.

Cut across the dotted line and lightly rub up and down the sides of the sachet. Hold the sachet with your thumb and fingers on the illustrated side and pour the required number of cubes into a sterilized, dried bottle.

POINT Rub the sides of sachet.

Rubbing the sides up and down allows air in the sachet makes the cubes come out easily.

Be very careful not to scald yourself!

Bring some water to a boil and let it cool slightly (70 degrees or higher*2). Pour this hot water into the bottle about two-thirds of the required amount. Place the nipple cover to prevent spillage and swirl the bottle well to dissolve the Cubes.

*2 In 2007, WHO (World Health Organization) and FAO (Food and Agriculture Organization of the United Nations) released “Safe preparation, storage and handling of powdered infant formula: guidelines,” and in June 2007, under the guidance of the Ministry of Health, Labor and Welfare, the recommended temperature for the preparation of powdered infant formula was revised from the conventional 40-50 degrees to 70 degrees or higher.

Tip: Moisten the cubes with hot water.

To dissolve the cubes efficiently, start swirling the bottle when the moistened cubes begin to disintegrate.

Using the scale on the bottle, measure the required amount at the border between the bubbles and the milk.

Add more water (boiled or boiled and then slightly cooled) to the desired amount. You will be handling hot water. Do not prepare the milk near your baby.

Attach the nipple and lightly swirl the bottle. Stand the bottle in water to cool the milk to about 40 degrees. Make sure that the milk is cooled to around body temperature before feeding.

Sprinkle a few drops on the inside of your wrist. If it feels warm, not hot or cold, around 40 degrees, it is ready.

Fill the nipple with the milk. Loosen the cap as necessary. Make sure that the milk comes out nicely. The nipple must stay filled while feeding.

Tip Burp your baby after feeding!

After feeding, hold your baby with their chin resting on your shoulder, and lightly pat or rub their back up and down to burp them to expel air.
