Lactose intolerance means the body has difficulty digesting lactose, the sugar in milk and dairy. It’s different from a milk allergy, and understanding the difference helps parents manage it safely.

Common signs after dairy include tummy pain, bloating, gas, and loose stools. Unlike a milk allergy (an immune reaction that can be serious), lactose intolerance causes digestive discomfort rather than an allergic response.

Managing it:

• Many children tolerate small amounts of dairy, or dairy taken with other food.
• Hard cheeses and yoghurt are often better tolerated than milk.
• Lactose-free milk and dairy alternatives are widely available.
• Because dairy is a key source of calcium, don’t remove it without ensuring calcium comes from other sources — ideally with guidance.

If your child has ongoing digestive symptoms after dairy, see a pediatrician to confirm the cause and protect their nutrition.
