Baby's Poop

April 4, 2025

What should I look for in my baby’s diaper? On the day of birth your infant should have at least 1 wet and 1 dirty diaper (called Meconium).  These dirty diapers will continue for another 2-3 days until the bowel movements change again when the mature breast milk comes in or the baby’s bowels adjust to the milk based formula, depending on feeding method.Please be sure to track or chart wet and dirty diapers for your pediatrician and IBCLC.

Day 1 of Life:

Day 2 of Life:

Day 3 of Life:

Day 4-5 of Life:

Days 6-8 of Life:

After the first week of life, the poop will change to mostly yellow, seedy and loose liquid stools.
At any point during the first few months of life, your baby’s bowel movements can change as a result of the breast milk they are receiving.

In some circumstances, babies may have small amounts of blood or mucous in their bowel movements.

If you notice any blood in the baby’s diaper, please schedule an appointment with the pediatrician so they can evaluate for possible allergy or other medical concerns.  Your baby’s bowel movements are an indicator of their well-being. It is important to give your physician and lactation consultant a history of the most recent feeding patterns, wet and dirty diaper count and color and consistency of the bowel movements. Monitoring your baby’s bowel movements is important, but not something to become overly concerned about unless you notice other significant changes at the same time. If you see changes in the baby’s poopy diapers and also see signs of excessive fussiness, excessive spitting up or other new behaviors that are causing disruption in sleep cycles, it might be time to have baby evaluated by a physician.
