This list of foods that cause diarrhea in breastfed baby is all you'll ever need to answer "what causes diarrhea in breastfed baby" we believe.

Foods that cause diarrhea in breastfed baby is the next topic that we cover in this article.

If you are wondering why we picked this one, it’s because after we’ve written few articles about breastfeeding on our website, we’ve received this email from a mommy asking “what causes diarrhea in breastfed babies?” – and since we were already covering anything-breastfeeding, we thought it’d be good to answer this query as well before we move on to the next topic.

That said, we want to share with you that why one should pay close attention to what she eats: the edibles that are being consumed have a direct effect on your baby as well, not just you.

Whatever that you’re eating or taking in into your stomach will be passed down to your baby from the breastmilk.

If the consumed fluid or food is healthy, your baby will grow and be normal – if, however, the consumed fluid or food is unhealthy, your baby will have to face many different issues, including diarrhea.

That said let’s get started with sharing a list of foods that cause diarrhea in breastfed baby.

Foods That Cause Diarrhea In Breastfed Baby:

Hey mommy, your question that asked “what causes diarrhea in breastfed babies?” is answered here in this part of the article.

1 – Dairy:


The very first food type you must stop consuming when breastfeeding your baby is a dairy type, or dairy products.

Dairy products have lactose, which in most cases, is hard for babies to digest – their digestive system isn’t as strong as yours and may leave your baby in stomachache or diarrhea.

However, yogurt is okay if you want to add dairy to your diet. Greek yogurt is one of the best ones.

2 – Greasy foods:


Greasy, fried, or oily foods go hard on the stomach and make digestion slow, even in matured people.

The fact that your baby’s digestive system is only 2/10 powerful and strong than yours is the reason you must stop taking in greasy or oily foods.

3 – Fatty foods:


Foods that have lots of fats are also hard to digest and takes time to be fully dissolved in your system.

Your baby here again isn’t capable of digesting fatty foods.

4 – Raw fruits and vegetables:


If you try to consume edibles raw, the amount of fiber found in them is much more than that of when they are cooked or prepared.

Fiber, in case you don’t know of, can change the speed of how fast your body performs digestion – more the fiber, slower the digestion.

For this very reason, you are not advised to eat raw vegetables and fruits before breastfeeding if you want your baby to be safe from diarrhea and things like it, i.e. stomachache.

5 – Spicy foods:


The next very dangerous type of foods you can consume while breastfeeding is a food type that has spices.

Spices can really affect the stomach and digestive tract – only the strongest of systems can fight back the effects of spices on your digestive tract.

As babies have a very weak system, it is strongly advised to keep them away from foods that are spicy.

6 – Whole grains:


Whole grains are not digested easily; they take some time.

This is another food type you must avoid.

However, when your baby is 8-9 months old, you can introduce whole grains to your baby if you want.

Fluids That Cause Diarrhea In Breastfed Baby:

Next comes the list of fluids that you must avoid if you want your baby to be safe from diarrhea.

1 – Tea and coffee:


Tea and coffee have nicotine, which if consumed and passed down to your baby, can leave him disturbed and fussy.

On top of that, the chances of diarrhea due to nicotine are also present and are on the peak.

This is why even smokers aren’t allowed to smoke while breastfeeding.

2 – Alcohol:


Alcohol needs no explanation we believe.

They are not only dangerous for your baby but for your own self as well.

You must put an end to its consumption as soon as possible.

3 – Soda:


Sodas have chemicals that go hard on the stomach, all the time.

Only strongest of systems can survive its effect

Your baby shouldn’t be exposed to sodas yet.

4 – Formulas:


Formulas, like powdered-milk instead of breastmilk, are very dangerous for your baby to consume.

I know this isn’t something you’d want to drink and then pass down to your baby by breastfeeding, but we found some importance of adding this one to this list as well.

You must not make your baby consume formulas for at least a year.

5 – Fruit juices:


Fruits and their juices have sugars which are hard for babies to digest – and these sugars can cause diarrhea and discomfort in return.

Babies younger than 5 months will most likely be affected by fruits and their juices, damaging their immature gastrointestinal systems.
