What Baby Poop Tells You: A Color and Texture Guide by Age

Stool appearance changes dramatically as infants grow. Here's a stage-by-stage reference for parents and caregivers.

Newborns (0–5 days): Meconium

• Color: Blackish-green, tar-like
• Texture: Sticky, odorless
• Composition: Amniotic fluid, bile, skin cells, lanugo
• Transition: Greenish-brown → yellow by day 3–5 as milk intake increases

Breastfed Infants

• Color: Mustard yellow, sometimes green-tinged
• Texture: Loose, seedy/curdy (like Dijon mustard)
• Frequency: Often after every feed (normal)
• Smell: Mildly sweet, yeasty

Formula-Fed Infants

• Color: Tan, yellow-tan, light brown
• Texture: Firmer, paste-like (peanut butter consistency)
• Frequency: 1–4 times daily
• Smell: Stronger, more adult-like

Toddlers (1–3 years)

• Color: Light yellow to brown
• Texture: Soft-formed, may contain identifiable food bits (corn, peas, raisins)
• Frequency: 1–2 times daily

Children & Adults

• Color: Medium to dark brown
• Texture: Formed, soft (Bristol Type 3–4 ideal)
• Frequency: 3×/day to 3×/week (wide normal range)

When to Call the Doctor

• Red/black (not from beets/iron) → possible bleeding
• White/clay/pale → liver/gallbladder issue
• Watery + fever/dehydration → infectious diarrhea
• Hard pellets + straining → constipation
• Mucus/blood + irritability → allergy/infection

Diet, medications, supplements, and illness all affect stool. When in doubt, photograph and consult your pediatrician.
