For sealed powder, it can go beyond a month. Nevertheless, you must not use it beyond the expiry date. An expiry date is not a suggestion; hence you should never forget that. The reason for this is that there will be a degeneration of nutrients after a while. Once you have opened it, the process is relatively faster.

Why you should not use expired leftover formula


No nutritional value

There is no nutrition in the recipe once it starts to deteriorate. Why should you give your baby milk that has no nutritional value? I suppose you would not wish that and after all your baby’s health is of more importance than saving money.

Your child may feel sick

Eating lousy food makes you ill, and therefore drinking spoilt milk will make your child sick. They will vomit and have diarrhea from the milk that has expired.

It may separate

Once expired, the consistency of the milk won’t be the same again. Even after mixing, it will be hard for you to get the mixture you initially wanted. It will be from the lumpy state that your baby will have to suck it twice as hard because it will not flow consistently from the bottom. It may cause blocking of the nipple of the bottle.

Critical infection

Cronobacter infection is an infection caused by leftover milk, which will put your baby at risk. This infection is likely to grow in your baby’s formula because it adapts to dry places. Blood poisoning is one terrible effect that is potential from this bacteria, which will threaten your baby’s life.

Uses of leftover formula powder

Unexpectedly there are lots of uses of leftover formula powder. Below are some of the benefits of baby formula powder.

Donate it to a food bank

You might be wondering how this is even possible. For your information, all yummy food can come as a result of the use of formula powder.

Anything unique is always excellent. Give yourself a treat by baking with the leftover formula. It is essential to look at the expiry date before using it. Use the formula powder to whip up a batch of cookies and muffins.

If you have no gloves, the formula powder will work out well as a cleanser and moisturizer for your hands. Only add some lemon juice to the powder because the lemon helps to clean while the milk powder scrapes off the dirt.

Washing your clothes

Stains in our clothes sometimes give us a hard time as we hardly try to get rid of them. All you have to do is to mix the formula with water, then soak your clothes in it overnight. Some people bet that this method removes stains at all without disappointment. It also works for white cotton. When it is done soaking, you can wash your clothes as usual and look how the stains will be getting off.
