What Is The Pink Spot In The Baby Diaper?

Before you try and figured out what is the pink spot in the baby diaper, I recommend you read this article first about the orange spot in the baby diaper. The reason I recommend you reading that article first because what you are seeing might or might not be blood. Other things can usually be confused for blood. What you are looking at might be a very light spotting which can indicate anything. If you see a huge amount of blood then go to the emergency room, because it is something very serious. If this is your occasional blood spotting then read on.

When I Saw Blood With My Baby – Her Constipation Problems

I was always wary of bleeding when it comes to my little Lilyanna. It is one of the parents biggest fears after all. Right now, she is 18 months old and recently I saw her first “spotting” on her diapers. It made my heart jump a little. I literally thought it was an infection. However, later my wife and I both realized that she is simply constipated.

This hasn’t happened a lot before because Lilyanna was still on breast milk. When she switched to formula milk, she was slightly constipated, but there was still no blood. Recently we decided to let her try other types of food like rice noodles, and she spotted a little. As she ate more solid foods, the chance of her constipating for a couple of days was happening more often. The obvious solution is to give her more water.

The problem with my daughter is that she doesn’t like to drink water. It doesn’t taste good after all, so she would generally tend to resist it. Some people suggest that we mix in small amounts of glucose so the water tastes a little better. However, I don’t really want my daughter to rely on sweet tasting stuff to get herself hydrated. As her father I use a lot of different methods to make sure my daughter gets some water into her system.

My daughter is naturally curious about a lot of things. One day, she was watching me drink a can of sprite. Of course, I am not going to let her drink any kinds of soda considering how many horrible health problems it causes in the long run. However, since my daughter has never drank sprite before, this was my chance to “trick” her.

With that thought in mind, I thoroughly rinsed my sprite soda can with hot water, then I filled it with clean water for my daughter to drink. My daughter happily drank all the water in the sprite soda can as if it is the most delicious thing in the world.

Normally, my wife will shout until she is red in the face in order to “force” a few drops of water down my daughter’s throat. However, in my case, it was a piece of cake.

This way, my daughter’s constipation problem was solved and blood no longer reappeared. Soon, she got tired of the soda can. There are still a lot of different types of bottles that she is curious about, so as long I get creative about it, having her drink water is never an issue anymore.

Constipation generally doesn’t affect purely breastfeeding newborns. Unlike my daughter, maybe your child didn’t have constipation problems. If it is something else bothering your child then read on.

Is The Breastfeeding Mother Bleeding?

Sometimes when you see blood in your baby’s diaper, it doesn’t necessarily mean that your baby is having a problem. At times, breastfeeding babies might be drinking her mother’s blood. As an end result, you might see blood ending up in your baby’s diaper.

The reason why a breastfeeding baby is drinking her mother’s blood is simply because her nipples are cracked. When the baby drinks from a cracked nipple, some of the blood ends up in her digestive tract. Even though a cracked nipple sounds pretty painful, some breastfeeding mothers might not feel any pain. This is why the crack is not obvious in the first place. Quite often you will have to search for it.

You might be asking, “why isn’t the poop pitch black after the blood got digested?” The answer is simple. The blood is only partially digested or not digested at all. Purely breastfed babies have very runny poop. The blood most likely passed through the intestines before it can a chance to be completed digested. That is why you see reddish blood instead of black.

One thing you can be sure of is that it is not harmful for the baby if she swallowed some of the mother’s blood. The only exception is if the breastfeeding mother developed “thrush” on her cracked nipples. In that case, the baby will also get infected by this fungi. Thrust is pretty painful. You know you and your baby have it if you  see mysterious white spots in the baby’s mouth and throat area.

Do You Have A Newborn Daughter?

This might sound funny, but some baby daughters actually have a slight early “period” when she is still a newborn. This happens when the hormones from the mother are passed onto the newborn. It might seem a little scary and strange, but once the baby’s hormone levels go back to normal, the bleeding will also go away.

Do You Have A Baby Son?

If your son has gone through circumcision (removing the foreskin on the penis), then sometimes there will be a little blood in the diaper. It shouldn’t be too much though.

Does Your Baby Have Diaper Rashes?

diaper rash

Don’t get me wrong. Not every baby that develops diaper rashes will actually bleed unless it is already very serious. However, if the rashes come along the following symptoms then you know it is serious:

  • Heavy bleeding, or bleeding that is happening very often
  • Your baby looks sick
  • Your baby is feverish
  • Your baby is bruised easily

Talk to your pediatrician in this scenario.

Does Your Baby Have Allergies?

Some babies are allergic to cow milk and soy milk. This can cause the baby to have inflammation in the intestines. You might be thinking that you haven’t fed your baby any of that. However, if you are a breastfeeding mom, you can’t eat any of that either. It passes directly to the baby.

If you eat outside or order takeout often, just realize that vegetable oil commonly has soy in it. If your baby has allergies, it is highly recommended you make your own food so you know what you are eating.

Oversupply Of Breast Milk – Causes Bleeding

If you thought you read that wrong, let me confirm the fact that too much breast milk can lead to bloody poop. Normally, good amount of breastmilk decreases the chances of bleeding because of the lower chance of allergies and infections from the immune system boost.

However, too much of a good thing can be a bad thing. Oversupply of breast milk is actually a problem even though it sounds beneficial.This is a relatively rare problem. Not many breastfeeding mothers are actually having an oversupply of milk. However, you can tell if you have an oversupply of breastmilk if you have the following:

  • Your baby seems to be choking on your breast milk (because of overflow)
  • Your baby seems to “bite” on your nipples a lot as if she hates it
  • Your baby has a lot of gas problems, and the poop is greenish, bloody and slimy
  • Your baby is getting heavier pretty fast but always seems hungry

Why Does Oversupply Cause Bleeding?


Why does bleeding happen? The reason is because the baby is not drinking enough hindmilk, or fatty breastmilk to be exact. Breast milk can be into two categories:

  • Foremilk (flows out first)
  • Hindmilk (flows out later)

Everytime you start your breastfeeding routine, your baby first drinks the foremilk. As she keeps drinking, theoretically, the hindmilk will flow out after the foremilk finishes.

The reason breastmilk is classified like that is more than just because one comes out first, and the other comes out later. The foremilk tends to be more “watery” so it flows through the gastrointestinal tract faster. The hindmilk tends to be “thicker” and fattier.

The reason this is important is because when a breastfeeding mother produces an oversupply of breast milk, the baby is drinking so much foremilk, she would be full before she has a chance to reach the hindmilk. In other words, your baby is getting more “watery” low fat milk instead of the “thicker” high fat milk.

You might be thinking that it should be a good thing that your baby doesn’t get “fat” from the milk, because fat is normally a bad thing right? In this situation, that is quite the opposite. You see, the reason why oversupply of milk causes bleeding is because your baby is not having a chance to digest the fast running foremilk.

You see, milk has a lot of sugar whether its foremilk or hindmilk. If none of that milk gets digested by your system, then the bacteria in your baby’s gut will feast on it. Bacteria produces a lot of acidic waste-products when they feasts on sugar (which is why your teeth gets cavities by the way). In other words, with all that undigested milk flowing around, the bacteria in your baby’s gut will punch a hole in there, and cause blood to flow.

The solution to all of this is for your baby drink more of the fat in the hindmilk. The fat in hindmilk will slow down the flow of breast milk because of the fatty content.
The key is to let the milk stay in the beginning part of the small intestine longer so that the enzymes (lactase for example) can break down the lactose sugar before they reach the bacteria further down the intestinal path.

Basically The Solution Is To Lower The Supply Of Breast Milk

In order to lower the amount of breastmilk, it is important for the breasts to build up a specific protein that signals the body to stop producing breast milk. The procedure works like this:

    1. Let your baby feed on one breast, (lets say the right side breast for example.)


  • Let your baby finish on one breast without cutting her off


  1. Wait 120 minutes or roughly 2 hours before feeding her with the other breast.
  2. If she wants milk again before 120 minutes are up, then simply feed her with the same breast from step 1 (in our example, that would be the right breast)
  3. If the pressure is too much on the other breast while you are waiting for the 120 minutes to finish, release a barely enough of breast milk with a pump to reduce the pressure. However, do not pump out all of the milk because you want your breast to build up the milk inhibiting protein. This protein decreases the amount of breast milk your breast makes. This protein won’t do its magic if you pump out all of your milk, because you need a high concentration of this protein in the breast to signal the body to stop making more milk.
  4. If all that still doesn’t work then consult your lactation consultant

Physical Injuries Can Also Cause Bleeding – Straddle Injury

This usually happens when your child is old enough to play and ride on something. They might hurt themselves while straddling something like a bike seat, wooden horsie or a seasaw for example, and bruise themselves at the genitals (private area).

If you see these signs in the groin area (between the legs) then it is most likely straddle injury:

  • Bleeding in the groin area
  • Bruises (and swollen like a hematoma)
  • Swelling
  • Having problems peeing (more serious)

Go see your pediatrician the moment you have a chance to have the injury checked out.

Vitamin Drops??? – Maybe A Source Of Bleeding

Some parents mentioned to me that vitamin D drops causes their little babies to develop blood in the poop. It has never happened to my little daughter even though she was on vitamin D for a very long time. However, if you can’t seem to find the reason for the blood in your baby’s diapers then try taking out the vitamin drops to see if anything changes. Just keep in mind that Vitamin D is important for a child’s development so double check with your pediatrician to be sure.
