Babies are born with the lactase enzyme and most lactose intolerance does not occur until age 3 or older if at all. Symptoms can be bloating, cramps, diarrhea
and poor growth
. Some races such as asians and african americans are more susceptable to lactose intolerance than caucasians.
2%-3% of infants have milk allergy
and the good news is that many of them outgrow in by 3-5 years of age. Milk allergy is actually the body's immune system recognizing cow milk protein
in the intestines as a foreign substance and causing symptoms like loose, sometimes bloody stool
, irritability, vomiting
and food refusal. This usually occurs in the first few months of life. The incidence of milk allergy is lower in breast fed babies than formula
fed babies, but some babies react to the cow's milk protein transferred through the mother's milk from the dairy in the mother's diet
. Breast feeding
is best and you can continue if you restrict or eliminate milk and dairy products from your diet. Just make sure you are getting enough calcium
from non-dairy sources!
