Why do I need to learn all about my babies poop?

A babies poop can alert you to various health issues such as a stomach bug, allergy or even more serious medical conditions.

This guide is not a substitute for an assessment from a medical professional. Please seek the advice of your healthcare professional if you have any concerns about your baby!

How often will my baby poop?

Breastfed babies can poop anywhere from after every feed to once in 7 days. This is totally normal. Formula fed babies will poop more often, usually after every single feed. This will continue for both breastfeeding and formula fed babies until about 6 weeks when their digestive systems mature.

Please discuss with your health care provider what they expect in terms of frequency.

Poop Texture

So not only is the color of babies poop important to recognizing any issues but the consistency can also be indicative of a problem. Here are some textures you may come accross:

Normal Poop

Babies normal poop is soft, slightly runny in texture. If you are breastfeeding it may also have a seedy appearance.

Mucous in Poop

This can be indicative of an allergy or an infection. In babies who are teething and swallowing excessive drool it may be normal.

My daughter actually had a sensitivity to egg and dairy while I was breastfeeding and her poop VERY VERY noticeably contained large amount of mucous. Please seek the help of a physician if this is occuring.

Loose Baby Poop

Diarrhea is a main concern in babies because they can very easily become dehydrated. Unfortunately it can be somewhat difficult to pick up in newborns as their stool is already quite loose.

If your baby is having a much more liquid stool than usual, especially if accompanied by an increased frequency (3 or more times in 24 hours is a good rule of thumb) please seek the advice of your physician.

Constipated Baby Poop

Young infants can sometimes appear to be struggling to poop. Sometimes this can be normal as their digestive tracts are not yet mature.

If your baby has hard, pellet bunny rabit poop, it could be indication of constipation. Please speak to your physician as this could have various causes.

Babies First Poop

Your babies first poop is known as meconium and usually occurs in the first 24 hours after birth. Sometimes a baby can poop while in the uterus, and your baby will need to be monitored closely by the health care team once after being born in case they inhailed any of it into their lungs. This sounds scary, but is actually a fairly common occurence – it happened to my daughter!

What does meconium look like?

Meconium is a very dark green, almost black, tarry stool. It is very sticky and hard to get off when you wipe.

Pro Tip: Putting Vaseline on your babies bottom before they have their first poop will help make the clean up process a bit easier. Plus it will save their little bum from irritation caused by rubbing the area.

How long does meconium last?

Meconium will only last for a few days at most and then it will transition to babies normal poop.

Pro Tip: Apply baby Vaseline or another ointment to your babies bottom before they have their first poop. Meconium is so sticky it can be hard to get off and all that rubbing action can irritate your babies skin, this makes it SO much easier!

Poop By Color

Now that we have the first poop out of the way, the easiest way to discuss the different possible poops your baby may have is by color. Sort of paint by poop color guide if you will. We will start this color guide based on the normal types of poops and then move on from there.

This poop color is the normal and expected color of breastfed babies. It can also be seen in formula fed babies and is considered normal.

Brown – Orange Baby poop

This color is normal and expected for formula fed babies. It can also be seen in breastfed babies if mom has eaten a lot of orange/red dye containing foods. A baby who has started eating solids orange in color may also experience this.

Dark Green Baby Poop

A baby who is taking iron will often have dark green poop – similar to adults who take iron supplements. A baby who is on formula that is fortified with iron may also experience dark green poop.

Green – tan baby poop

There are many reasons for green-tan baby poop that can be normal:

  • breastfeeding or formula feeding baby if the consistency remains the same
  • teething babies

Sometimes green- tan baby poop can indicate:

  • a stomach infection
  • a allergy, especially if accompanied by mucous

Bright yellow Baby Poop

Certain medications baby might be on can make a babies poop bright yellow. If mom is taking certain medications and breastfeeding it can have the same effect. Please make sure to check with your healthcare provider that any medication you are taking is safe for a breastfed baby.

Bright yellow can also be indicative of a stomach bug.

Bright Green Baby Poop

In breastfeeding babies it can mean that your baby is getting too much foremilk and not enough of the fatty hind milk. To correct this completely empty the breast when feeding, express some milk before feeding baby to get rid of some of the foremilk and start with the same breast you finished with on the previous feed before switching sides.

Black or Very Dark Baby Poop

This color is normal for a baby on iron or drinking iron fortified formula. This color is also normal for meconium as discussed above, but if it continues for more than 3-4 days you need to speak with your physician.

Dark stools can also be a sign of a GI bleed, so be sure to discuss with your physician if your baby is over 4 days old and not taking any iron.

Red Baby Poop

While alarming it can actually be normal in some circumstances such as:

  • A breastfed baby where mom is experiencing bleeding nipples
  • A constipated baby – altho constipation is not normal and needs to be corrected it can lead to small flecks of blood in the babies poop

Red poop accompanied by mucus can be indicative of an allergy.

If your baby is experiencing large amounts of red coloring in their stool, it could be indicative of an active bleed along their GI tract. Please seek medical attention promptly.

White Baby Poop

Chalky white stool needs to be assessed by a medical physician promptly. It can be indicative of gallbladder and liver diseases.

Grey Baby Poop

Grey baby poop also needs to be assessed by a medical physician promptly as it can be indicative of gallbladder and liver diseases.

This may be normal if your baby has just started to eat solids and will correct itself as their digestive tract matures.
