Preparing infant formula correctly is one of the most fundamental tasks of early parenthood, directly impacting your baby’s nutrition and safety. To prepare Kendamil formula properly, you must follow a precise sequence of hygienic steps: sterilising your equipment, boiling and cooling water to the exact temperature specified on your specific tin, and using the provided scoop to measure the powder without packing it down. Adhering strictly to the manufacturer’s instructions on the packaging ensures your baby receives the correct balance of hydration and nutrients. While the general process remains consistent, subtle differences in scoop sizes and water volumes exist across different product stages, making it essential to verify the feeding guide on your current tin before mixing.
What You Need Before Preparing the Bottle
Before you begin mixing a feed, gathering all the necessary tools and preparing a clean workspace prevents contamination and makes the process seamless. You will need fully cleaned and sterilised bottles, teats, collar rings, and caps. Sterilisation can be achieved using a steam steriliser, cold-water sterilising tablets, or by boiling the components in water according to the manufacturer’s instructions.
The water used for preparation must be freshly boiled and then cooled to the temperature recommended on your specific Kendamil product label. This temperature is crucial because water that is too hot can damage delicate nutrients, while water that is too cool may not dissolve the powder effectively. Always check the instructions on your specific tin, as different formulations may have unique temperature requirements.
Keep your Kendamil formula tin nearby, ensuring you use only the specific measuring scoop packaged inside that exact tin. Scoop sizes can vary between product lines and stages, so swapping scoops between different tins can lead to incorrect dosing.
Finally, prepare a clean, sanitised surface to assemble the bottle. Wash your hands thoroughly with soap and warm water, drying them with a clean towel or paper towel before touching any sterilised equipment or the formula powder. Maintaining this hygienic barrier is a vital step in protecting your infant’s developing immune system.
Step-by-Step Instructions for Mixing Kendamil Formula
Once your preparation area is clean and your tools are ready, you can begin the mixing process. Accurate measurement of both water and powder is essential to ensure the formula is neither too concentrated nor too diluted.

Step 1: Measure the Water. Pour the boiled water, which has been cooled to the temperature specified on the product label, directly into your sterilised feeding bottle. Always read the volume markings on the side of the bottle at eye level to ensure precision. It is critical to add the water to the bottle first before adding any powder, as this ensures the final volume and concentration are correct.
Step 2: Scoop and Level the Powder. Open your Kendamil tin and locate the provided scoop. Gently scoop the formula powder out of the tin, allowing it to heap slightly. Use a clean, dry, sterilised knife or the built-in leveler on the rim of the tin to sweep away the excess powder, creating a flat, level scoop. Never press, pack, or tap the scoop against the side of the tin, as compacting the powder adds too much formula to the feed, which can strain your baby’s digestive system.
Step 3: Add the Powder and Secure the Cap. Carefully transfer the exact number of level scoops required for your baby’s feed into the bottle containing the measured water. Refer directly to the feeding table on your packaging to confirm the correct number of scoops for the volume of water you poured. Once the powder is added, immediately place the sterilised teat and collar onto the bottle, securing the cap tightly to prevent leaks during mixing.
Step 4: Dissolve the Powder. Gently swirl or shake the bottle to mix the powder and water thoroughly. A gentle, circular swirling motion followed by a light shake is usually sufficient to dissolve the powder completely. Avoid shaking the bottle vigorously, as this introduces excessive air bubbles into the milk, which your baby might swallow, potentially leading to gas, colic, or general discomfort after feeding.
Checking the Temperature and Feeding Safely
Before offering the prepared bottle to your baby, verifying that the milk is at a safe temperature is a critical safety check. Pour a few drops of the mixed formula onto the inside of your wrist. The skin here is highly sensitive, allowing you to accurately judge if the liquid is lukewarm, which is the ideal feeding temperature. If the formula feels hot against your skin, let the bottle cool further under cold running water before testing it again.
Never use a microwave to heat or warm infant formula under any circumstances. Microwaves heat liquids unevenly, creating localized “hot spots” that may not be detectable when shaking the bottle but can severely burn your baby’s mouth and throat. If you need to warm a bottle, place it in a bowl of warm water or use a dedicated bottle warmer, checking the temperature on your wrist afterward.
When feeding, hold your baby in a comfortable, semi-upright position rather than lying flat. This position helps support safe swallowing and reduces the risk of choking. Tilt the bottle at an angle that ensures the teat is completely filled with milk before your baby begins to suck, which prevents them from swallowing excess air during the feed.
After your baby has finished feeding, discard any leftover formula remaining in the bottle within the timeframe specified on the product label. Bacteria from your baby’s saliva can enter the bottle during feeding and multiply rapidly in the warm milk. Never save, refrigerate, or reheat leftover formula for a subsequent feed, as this poses a significant contamination risk.
Adjusting the Powder-to-Water Ratio for Your Baby's Age
As your baby grows, their nutritional requirements and digestive capacity change, which is why infant formulas are often divided into different stages. Kendamil offers distinct stages, such as Stage 1, Stage 2, and Stage 3, each tailored to specific age ranges and developmental milestones. The scoop sizes, powder densities, and recommended water-to-powder ratios can vary significantly between these stages and specific product lines.
Always consult the feeding guide table printed on the back of your specific Kendamil packaging to determine the correct proportions for your baby’s current age and weight. This table serves as the primary authority for preparation, as it is updated by the manufacturer to reflect the exact nutritional profile of that specific batch and stage.
It is vital that you never alter the water-to-powder ratio by adding extra scoops or using less water than directed. Making the formula too concentrated can cause dehydration, constipation, and put undue stress on your baby’s kidneys. Conversely, diluting the formula by adding extra water or fewer scoops deprives your baby of essential calories and nutrients, potentially impacting their growth and development.
If you feel your baby requires a different feeding volume or frequency, or if they exhibit signs of discomfort, consult a pediatrician or a registered dietitian. A qualified healthcare professional can provide personalized guidance based on your baby’s unique growth curve and dietary needs, ensuring you make safe adjustments.
Cleaning and Storing Kendamil Formula Properly
Maintaining the quality of the formula powder and keeping your feeding equipment sterile are essential components of safe feeding practices. Store your opened Kendamil tin in a cool, dry place away from direct sunlight, heating vents, or appliances that generate heat. In warm or humid climates, such as Singapore, finding a stable, dry pantry space is particularly important to prevent moisture from affecting the powder.
Check the packaging for the manufacturer’s specific instructions regarding how long the formula remains safe to use after the tin has been opened. It is a helpful practice to write the date of opening directly on the lid or label with a permanent marker to ensure you do not use the powder past this recommended timeframe.
Do not store the formula powder or the open tin in the refrigerator. The temperature fluctuations from opening and closing the refrigerator door create condensation inside the tin, which can cause the powder to clump, spoil, or harbor bacteria.
After every feed, thoroughly wash all bottle components, teats, and the measuring scoop in warm, soapy water, using a dedicated bottle brush to remove any milk residue. Rinse them thoroughly before sterilising them again, ensuring the scoop is completely dry before placing it back into the tin for the next use.
Frequently Asked Questions (FAQ)
Can I use tap water to prepare Kendamil formula?
Yes, tap water can generally be used to prepare Kendamil formula, provided it has been boiled first to eliminate potential pathogens. Bring fresh tap water to a rolling boil and then allow it to cool to the specific temperature recommended on your formula packaging before mixing. If you choose to use bottled water, you must verify that it is explicitly labeled as suitable for infant feed preparation, as some bottled waters contain mineral levels that are too high for an infant’s kidneys. Avoid using unboiled tap water, untreated well water, or artificially softened water, as these sources may contain contaminants or mineral imbalances that are unsafe for your baby.
Why does the formula sometimes look clumpy or leave residue?
Occasionally, you may notice small clumps of powder or a slight residue on the inside walls of the bottle after mixing. This phenomenon can occur due to minor variations in water temperature or the natural characteristics of the ingredients used in the formula. To resolve this, ensure you are checking the water temperature with a thermometer or following the label’s cooling instructions closely, as water that is too cold may not dissolve the fats and proteins efficiently. If you observe persistent, unusual clumping, severe discoloration, or an abnormal odor when opening a new tin, stop using the product immediately and contact the manufacturer for guidance.
Is it safe to prepare bottles in advance?
Preparing formula fresh for each individual feed is always the safest and most recommended approach to minimize the risk of bacterial growth. However, if you must prepare a bottle in advance for travel or night feeds, you must strictly follow the manufacturer’s guidelines regarding safe refrigeration storage times and cooling procedures. Typically, prepared formula must be stored in the back of the main refrigerator compartment (not the door) and used within the timeframe specified on the label. Any prepared bottle that has been left at room temperature for more than the recommended limit, or has been partially consumed by your baby, must be discarded immediately to prevent contamination.
