Research shows that what you eat affects your milk only slightly. Babies love the flavors of foods that come through the milk. Sometimes a baby may be sensitive to something the mother eats, such as dairy products like eggs or milk and cheese.
Watch your baby for the symptoms listed below, which could indicate that your baby has an allergy or sensitivity to something you eat:
- Diarrhea, vomiting, green stools with mucus and/or blood
- Rash, eczema (EG-zuh-muh), dermatitis, hives, dry skin
- Fussiness during and/or after feedings
- Inconsolable crying for long periods
- Sudden waking with discomfort
- Wheezing or coughing
These signs do not mean your baby is allergic to your milk, only to something that you ate. You may need to stop eating whatever is bothering your baby or eat less of it. You may find that after a few months you can eat the food again with better results.
Talk with your baby\’s doctor if you notice any of the symptoms listed above. If your baby ever has problems breathing, call 911 or go to your nearest emergency room.
