Detailed Explanation by Color

Dark Green/Black (Meconium) - Normal

This is meconium, passed in the first 1-3 days after birth.

Characteristics:

• Sticky, tar-like texture
• Almost no smell
• Made of amniotic fluid, mucus swallowed in the womb

If meconium continues beyond 3 days, consult your pediatrician.

Yellow/Mustard - Normal

Typical stool color for breastfed babies.

Characteristics:

• Bright yellow to mustard color
• Contains seed-like particles
• Loose, soft texture
• Slightly sour smell

This color is a good sign that baby is getting enough breast milk.

Tan/Brown - Normal

Typical for formula-fed babies or babies starting solids.

Characteristics:

• Tan to light brown
• Firmer than breastfed baby stool
• Peanut butter-like consistency
• Slightly stronger smell

Greenish-Brown - Normal

Appears for various normal reasons.

Causes:

• Transition from meconium to regular stool
• Iron-fortified formula
• Iron supplements
• Green vegetable baby food

No need to worry.

Bright Green - Usually Normal

Bright green stool has several causes.

Common causes:

• Foremilk/hindmilk imbalance (breastfeeding)
• Fast gut transit time
• Viral infection
• Food sensitivity

Check points:

• Usually normal if no other symptoms
• Consult pediatrician if persists 2+ weeks

Orange - Normal

Common in babies who've started solids.

Causes:

• Carrots, sweet potatoes, squash
• Some formula ingredients

It's just food color coming through - no worries.

Red Spots/Streaks - Caution

Seeing red can be alarming, but it's not always dangerous.

Common causes (usually minor):

• Small tears around the anus
• Minor bleeding from constipation
• Mom's nipple bleeding (mixed in milk)

Warning signs:

• Significant bright red blood
• Blood with jelly-like mucus
• Baby seems in pain or very fussy

If you see red, consult your pediatrician.

Black (After Meconium) - Warning

Black stool after the meconium period needs attention.

Possible causes:

• Upper GI bleeding (stomach, esophagus)
• Swallowed blood (rarely from mom during feeding)

Action: See doctor immediately

Note: Dark green stool from iron supplements is normal.

White/Gray - Warning

This is the most concerning color.

Causes:

• Bile not reaching the intestines
• Possible biliary atresia
• Liver problems

Characteristics:

• Pale, colorless
• Gray or white
• Clay-like texture

White/gray stool requires immediate medical attention. Early detection of biliary atresia is crucial.

What Else to Check with Color

Don't just look at color - check these too:

1. Consistency

• Is it similar to usual?
• Not too hard or too watery?

2. Frequency

• Any sudden increase or decrease?
• Breastfed: 1-10 times/day
• Formula-fed: 1-4 times/day

3. Smell

• Unusually foul compared to normal?

4. Baby's Condition

• Eating well?
• Not fussy?
• No fever?
