Sometimes, the body mistakes soy as a harmful substance and tries to fight it off and this leads to allergies. Soy milk allergy in infants is noticed at around 3 months, but most children outgrow this by the time they are two years of age.
It is important that you avoid the use soy as a first food option unless advised by the doctor. If a mother is breast feeding and the baby is allergic to soy, she will also have to avoid eating soy products during the entire term of feeding the baby.

These include acne, rashes, itching, swelling, hives, nasal congestion, asthma-like symptoms, shortness of breath, anaphylaxis, fever blisters, colic, diarrhea, conjunctivitis, fever, weakness, nausea, and low blood pressure. A soy milk allergy usually appears a few hours after the infant is exposed to milk. There are many different kinds of rashes that could indicate that your baby is allergic to milk. The common types of rashes to look out for are hives, acne, and eczema; that can occur on any part of the baby's body. However, a soy milk allergy rash is mostly concentrated around the baby's mouth.
