Can Eating Spinach Make Breastfeed Baby Poop Green?


When babies are born, their bodies go through an adjustment period as they get used to their new surroundings and diet. One of the biggest concerns for new parents is the color, texture, and frequency of their baby’s poop. While it can be alarming to see a change in your baby’s bowel movements, it is important to understand that this is a normal part of their development.

One common question that new mothers have is whether eating certain foods, such as spinach, can affect the color of their breastfed baby’s poop. In this article, we will explore the possible link between eating spinach and green poop in breastfed babies.

The Nutritional Benefits of Spinach

Before we dive into the topic, let’s first understand why spinach is often recommended as part of a healthy diet for both mothers and babies. Spinach is a leafy green vegetable that is rich in essential vitamins and minerals such as vitamin A, C, K, iron, and folate. These nutrients are not only important for the mother’s health but also for the growth and development of the baby.

When a mother eats spinach, these nutrients are passed on to her breast milk and then to her baby. This is why it is often recommended for breastfeeding mothers to have a well-balanced and nutritious diet.

The Possible Link Between Spinach and Green Poop

Now, let’s address the main question at hand – can eating spinach make your breastfed baby’s poop green? The short answer is yes, it is possible.

As mentioned earlier, the nutrients from spinach are absorbed by the mother’s body and passed on to her breast milk. When a baby consumes this milk, they also receive these nutrients. However, in some cases, if there is an excess amount of spinach in the mother’s diet, it can cause a change in the color of the baby’s poop.

Is Green Poop Normal for Breastfed Babies?

Before you start panicking, it is important to understand that green poop is not always a cause for concern. In fact, it is quite common for breastfed babies to have greenish poop at some point in their development.

This is because breast milk is made up of various components, including foremilk and hindmilk. Foremilk is the milk that is produced at the beginning of a feeding session and contains more water and lactose. On the other hand, hindmilk is produced towards the end of a feeding session and contains more fat.

If a baby consumes more foremilk than hindmilk, it can result in a green color because of the higher levels of lactose. This is completely normal and does not require any intervention.

What Causes Green Poop in Breastfed Babies?

The color and consistency of a baby’s poop can vary depending on what they eat and how their body processes it.

In the early days of breastfeeding, a baby’s poop is usually greenish-black, sticky, and tar-like. This is called meconium and is made up of everything that your baby ingested while in the womb. As your baby starts to consume breast milk exclusively, their poop will gradually transition to a mustard yellow color with a seedy texture.

However, if your breastfed baby’s poop is consistently green in color, it could be a sign of something else. Some potential causes of green poop in breastfed babies include:

  • Consuming high levels of iron: Iron supplements or high levels of iron in the mother’s diet can cause green poop in breastfed babies.
  • Foremilk/hindmilk imbalance: If a baby is getting too much of the low-fat foremilk and not enough of the high-fat hindmilk, it can result in green poop.
  • Food allergies or sensitivities: Some babies may have an allergic reaction or sensitivity to certain foods that the mother has eaten, resulting in green poop.

Now that we understand what can cause green poop in breastfed babies, let’s take a closer look at whether spinach can be a contributing factor.

When to Be Concerned

While green poop in breastfed babies is usually nothing to worry about, there are certain instances where it can be a cause for concern. If your baby’s poop is consistently green and they also show signs of discomfort, diarrhea, or blood in their stool, it is important to consult a doctor.

This could be an indication of an underlying issue such as a food intolerance or infection. In this case, the green poop may not be solely attributed to spinach but rather a reaction to other substances in the mother’s diet.

How to Manage Green Poop in Breastfed Babies

If you suspect that spinach may be causing your baby’s green poop, there are a few steps you can take to manage the situation:

  • Decrease your spinach intake: If you are consuming a lot of spinach, try reducing the amount and see if it makes a difference in your baby’s poop color.
  • Try different cooking methods: Some babies may be able to tolerate cooked spinach better than raw. Experiment with different methods of preparing spinach, such as steaming or sautéing, to see if it makes a difference.
  • Elimination diet: If you suspect that your baby may have an allergy or sensitivity to spinach, you can try eliminating it from your diet for a few weeks and see if there is any improvement in their poop color.


In conclusion, eating spinach can indeed make your breastfed baby’s poop green. However, this is usually nothing to be concerned about as long as the baby is otherwise healthy and showing no other symptoms. As with any changes in your baby’s bowel movements, it is always best to consult a doctor if you have any concerns or notice any alarming symptoms.


How long does it take for spinach to affect the color of breastfed baby’s poop?

It varies from baby to baby, but typically you may notice the change within 24-48 hours after consuming spinach.

Does the green color of my breastfed baby’s poop indicate a problem with digestion?

Generally, no. The green color is often just a result of passing through the digestive system quickly. However, if you notice other unusual changes in your baby’s stool or behavior, consult a healthcare provider.

Are there any other foods besides spinach that can cause green poop in breastfed babies?

Yes, other green vegetables like kale, broccoli, and asparagus can have a similar effect due to their chlorophyll content.

Is there anything I can do to help my breastfed baby’s digestion if their poop is consistently green?

Ensuring that you’re well-hydrated, maintaining a balanced diet, and breastfeeding frequently can all support healthy digestion for your baby, regardless of stool color. If you have concerns, consulting a pediatrician is always recommended.
