đŻ Seeing red, raised, or irritated skin on your baby can feel alarmingâespecially when youâre already navigating feeding, sleep, and recovery.
Baby rashes have many causes. Some are related to normal newborn skin sensitivity or eczema. Others can be connected to food intolerances or allergies, especially when skin changes show up alongside other symptoms like reflux, mucousy or green stools, blood-streaked stool, or ongoing fussiness during or after feeds.
When weâre talking about food reactions in infants, dairy (cowâs milk protein) is the most common allergen affecting babies. For breastfed babies, this protein can pass through human milk and may cause symptoms in sensitive infants. That said, skin symptoms alone are rarely enough to diagnose an intoleranceâcontext matters.
This is why a whole-baby, whole-feeding picture is so important. Patterns over time, not one isolated symptom, guide next steps. And elimination diets should be thoughtful and supported, not rushed or fear-based.
If youâre wondering whatâs normal, whatâs worth watching, and when to seek supportâyouâre not overreacting. And youâre not alone đ
