When you feed your baby, only make enough in the bottle that your baby will consume. Once your baby is done, you cannot store the leftovers in the bottle for another time. The combination of saliva in the formula has made it a breeding ground for bacteria. Dump out the remnants.
You can prepare formula ahead of time and then refrigerate it. A prepared batch of formula can last 24 hours in the coldest part of your refrigerator. In other words, the back corner is better than the front or in the door as it is exposed to the temperature in the room more often. How much you prepare depends on how much your little one needs in a 24-hour period. For example, if your baby is 20 pounds, multiply that times 2.5. Your baby will consume 50 ounces in that period of time. All you have to do is pour the amount your baby needs for a feeding, warm it to 98.6 degrees Fahrenheit, and serve.
You cannot prepare Hipp Organic Formula, or any other formula, and then freeze it. The temperature can break up the components so that the texture is grainy and the fat separates. Shaking it after warming it up will not return it to its original texture.
How you store your baby formula is important. While you want to keep it handy, you want it to be in a place so that every sachet or container of Hipp remains fresh and full of nutrients. The wrong spot can impact the quality of the product.
You probably have a station on your kitchen counter dedicated to all the tools you need to feed your baby. Your drying rack has all of the nipples, rings, and bottles that are sanitized and ready to go. It is efficient to keep your formula in that area, but think before you commit to the spot. Is it dry? Is it at room temperature? Does it maintain room temperature or is there exposure from the sun from a window in that area?
It is important to keep your Hipp Organic Formula in a cool, dry place whether it is sealed or opened. A corner that is away from heat-emitting appliances is a good place. A cabinet or drawer will also serve the purpose. If you have more than one box, make sure that you place the one with the earliest expiration date toward the front.
The worst place to store powdered formula is in the refrigerator or freezer. Both of these have humidity within that can cause clumping. The powder needs to stay loose because clumps can actually give your baby too much of what they need. This can affect the balance of water to powder and do damage to your baby's kidneys over long periods of time.
