Old Formula: When Bottles Become Dangerous

Old Formula: When Bottles Become Dangerous

The old formula: When bottles become dangerous. There is a lot to remember when it comes to looking after a baby. As much as we may want to, there’s no way any of us can be perfect parents all the time, and most mistakes are unintentional. One mistake some parents make when it comes to formula feeding is feeding their baby a bottle of old formula, but what happens if a baby drinks old formula?

Thankfully, in many cases, nothing serious will happen; but if you suspect your child has consumed an expired or spoiled batch of milk, then take them immediately to the nearest emergency room for treatment.


Some symptoms that can indicate your child has consumed old formula are: diarrhea, vomiting, fever and dehydration. The milk from an old bottle of formula may also be sour or have a different color to it than fresh formula-colored like curdled cow’s milk.

What to Do if Your Baby Has a Reaction After Drinking Old Formula?

 In the majority of cases, once you have taken them to the hospital and they are given IV fluids, most symptoms will stop developing. This is because dehydration caused by an illness or vomiting can be made worse when milk becomes less nutritious. The main treatment for babies who drink expired milk is to make sure they are hydrated.

What if the Baby Still Has Some of the Old Milk in Their Stomach?

In most cases, even though your child might be vomiting and have diarrhea after drinking expired formula, it’s not necessary for them to go on a drip or take other medications – because you would expect these symptoms anyway from the illness.

The old formula may not be harmful, but it can still cause dehydration. If you are breastfeeding and feel like your milk is the culprit of an illness, talk to your doctor.

The Difference Between Colic and Dehydration

Sometimes it is hard to tell the difference between colic and dehydration. Both are common conditions in infants, but only colic is considered a disease. Colic happens when an infant has gas or trouble digesting food. Colic is usually treated with time, and over-the-counter medications like simethicone drops or Mylicon gas relief drops for fussy babies.

The Differences: Colic is a disease that can be cured after time and with the use of medications, while dehydration will only be cured after you drink water.

There Are Three Ways to Tell if Your Baby Might Be Dehydrated:

  • A sunken fontanel or a dry mouth. A sunken fontanel, or soft spot on your baby’s head, may be an indication that your infant is dehydrated.
  • An infant’s mouth can also be a good indicator of whether or not they are hydrated. If your baby has dry, chapped lips, then they may be dehydrated. 
  • You can also tell if your baby is dehydrated by looking at their diapers. If they have less than six wet diapers in 24 hours, then they might be dehydrated.

Parenting is hard work, and no parent can be perfect all the time, but knowing some of these common mistakes can help you, and your baby have a happier life.
