Are you concerned, and you don’t know what to do when the baby’s breath smells like sour milk?

Every change in your baby’s health and condition should be an utmost priority in the parenting realm.

Although infants try to communicate their discomforts or pains through cries and screams, they might not be capable of explaining minor details such as the bad breath.

As a result, it’s vital to be attentive to any sudden changes. 

Bad breath is a huge source of embarrassment for adults, and you can go to any lengths to get rid of it.

However, when it is a baby’s bad breath in question, it is difficult to know where to start.

So if you are wondering what to do when baby’s breath smells like sour milk, here are some simple remedies you can try.

What To Do When Baby’s Breath Smells Like Sour Milk

As tempting as it can be to ignore your baby’s bad breath, it is not the best course of action.

A baby’s bad breath can be an indicator of the state of their health and can even be a sign of something seriously wrong.

One common reason for bad breath is that the bacteria in your baby’s mouth is a reaction to food particles that have been there for a while, even near the tonsils.

Your baby’s mouth may also smell if they have eaten something smelly recently.

That sour milk lousy breath may also be caused by gastroesophageal reflux (GERD), as their fairly new digestive systems try to work through the food they’ve eaten.

GERD or Acid reflux is likely to make your baby very irritable, with lots of crying involved during feeding times. 

Typical signs that your baby suffers from acid reflux include lack of appetite, choking or gagging when feeding, vomiting, fussiness and heartburn.

If your baby already has teeth, bad breath can result from cavities, abscesses, and tartar build-up.

Poor dental hygiene and foreign objects inside your baby’s mouth can also be the cause of bad breath.

Also, chronic sinusitis is a potential cause of bad breath.

And worse, if it occurs concurrently with other symptoms such as cough, running nose, and nasal obstruction.

The latter primarily occurs when a piece of food is caught up in the nasal cavity. To remedy this, ensure your baby drinks sufficient water and oral hygiene.

Additionally, you might try clearing your child’s nose to get rid of the obstruction. If the condition doesn’t improve, always consult a pediatrician.

It’s not the end of the world just because your baby’s mouth smells like sour milk.

There are several things you can do to change this, which include:

  1. Wiping down their mouth after every feeding. You can do this with a soft, warm cloth while ensuring you cover the whole tongue and gum area.
  2. If your baby is already eating solid foods, try to keep them away from really smelly ones. You should also make sure that they rinse out their mouth with warm water immediately after they eat. Note that it’s vital to consult with a health expert before giving your little one solid foods.
  3. If you have a toddler with brush-able teeth, keep some baby toothpaste and a soft toothbrush handy. Ideally, you should make sure that your baby cleans their teeth after every meal.
  4. Make sure that your baby always has eyes on them so that they don’t end up putting foreign objects inside their mouth.
  5. Where GERD may be the culprit, the best thing you can do for your baby is make sure they are not lying on their back immediately after eating. It causes stomach acids to get into the esophagus leading to reflux. Instead, make sure that your baby remains seated upright for at least half an hour after they are done eating. You can also try feeding them smaller portions so that they have an easier time digesting the food. It also helps to have frequent feeding times during the day instead of just the three main ones. Luckily, most babies outgrow this reflex action after some time, and your baby could be back to normal by the time they are three months old.
  6. If you try all these remedies and the sour milk terrible breath still persists, it may be time to take your baby to a doctor. The doctor can tell if there’s a serious underlying condition causing this and offer a medical solution.

Naturally, babies are supposed to be perfect and smell amazing.

When that doesn’t happen, you may be racking your brain wondering what to do when baby’s breath smells like sour milk.

While it’s mostly not a reason for concern, it is important to know what’s causing it and how to get rid of your baby’s bad breath for good.

Frequently Asked Questions

Why Does My Baby Have Breath That Smells Like or Poop? 

In most cases, if your baby’s breath smells like fart or poop, it can result from underlying medical conditions such as GERD, diabetes, or inflammation of the sinuses.

And as mentioned, poor dental hygiene can be a reason. It’s possible to treat and remedy the above reasons, but it would be best to consult a healthcare provider. 

When Should Toddlers Use Toothpaste? 

Preferably at 18 months. Also, it would be best to start with small amounts of low fluoride toothpaste.

Also, unless your little one can spit, it would be best not to switch to adult toothpaste.

While there isn’t a hard rule for when toddlers should switch to fluoride toothpaste, pediatricians recommend switching toothpaste at age six.

Additionally, immediately the first tooth erupts on your baby’s gum, parents should use a small and soft toothbrush without toothpaste to prevent bottle tooth decay. 

Does Teething Make Baby’s Breath Smells Like Sour Milk?

Babies inhibit various signs of teething. And, in some cases, some parents might notice a change in their little one’s smell.

For example, a vinegary smell, mainly due to the baby’s drool or poop, could be a sign your toddler is teething.

Still, it would be best to check for other issues to determine the leading cause of the bad breath.
