I changed my baby's formula and their stool color and consistency changed. Is this normal?

Changes in stool color and consistency after a formula change are quite common and usually normal. Each formula has a different protein source (cow milk protein, hydrolyzed protein), iron content, and fiber structure, so temporary changes in stool are normal as your baby's gut adapts.
Generally:
- Consistency: New formula may cause thicker or more watery stools.
- Color: Green, brown tones, even grayish-green are normal.
- Frequency: May temporarily increase or decrease.
Consult your pediatrician if stools are consistently white/clay colored, red (bloody), or black and tar-like; or if your baby has fussiness, vomiting, rash, bloody mucusy stools, or slowed weight gain. These can indicate formula intolerance or allergy.
Usually within 1-2 weeks things settle. If your baby's overall condition is good, observing during this period is enough.
