Lactose intolerance is a problem that makes it hard to digest lactose. Lactose is a sugar that is found in milk and milk products. Some children don't make enough of an enzyme called lactase. This is used to digest lactose. When this happens, it can cause gas, belly pain, diarrhea, and bloating. This is not the same as a food allergy to milk.
Lactose intolerance affects different children in different ways. Some children cannot digest any milk products. Other children can eat or drink small amounts of milk products or certain types of milk products without problems. You can help your child learn how to avoid discomfort and still get enough calcium to build and maintain healthy bones.

Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems.
