There are several common misconceptions about lactose intolerance in babies that need to be debunked. One myth is that all babies who are fussy or gassy are lactose intolerant. In reality, these symptoms can be caused by a variety of factors, such as immature digestive systems or other food sensitivities.

Another myth is that lactose intolerance is always present from birth. However, lactose intolerance can develop over time and may not manifest until later in childhood or adulthood.

It's also important to note that lactose intolerance is different from a milk allergy. Lactose intolerance is the inability to fully digest lactose, the sugar found in milk, while a milk allergy is an immune system reaction to the proteins in milk.

It's crucial for parents and caregivers to work with healthcare professionals to properly diagnose and manage any potential lactose intolerance in babies, rather than self-diagnosing based on common misconceptions.
