Lactose intolerance in babies is usually temporary. Most often, it’s a situation in which the intestine, while still developing, has trouble digesting and absorbing lactose. This can cause gas. It can also occur after a stomach illness or diarrhea. There are two nutritionally complete lactose-free options from the makers of Similac that may help reduce fussiness and gas due to lactose intolerance:

• Similac Sensitive Lactose-Free*
• Isomil Advance soy-based formula

Permanent lactose intolerance is very rare in babies. You’ll want to discuss the situation with your health care professional before making changes to your baby’s diet.
