If you need to know which formula would suit your constipated baby best, one thing to note is that there’s no single formula that suits all infants.

What might be the best choice for another baby may give your infant gas or diarrhea, for instance? If you suspect your baby is suffering from severe constipation, it is important to consult a doctor as well.

Some babies may take a while to adapt to a switch in formulas. When choosing a new formula, the following points are worthy of consideration.

Be Aware of Your Infant’s Allergies

Lactose intolerance and milk allergies are more common in infants than you think. In such cases, lactose-based formulas should be avoided. Try using a soy-based formula instead.

Look Closely at the Nutrients

Babies need optimal nourishment for staying healthy. Infancy is a crucial stage in the development of their organ systems.

If you must formula-feed your infant, choose one that has components like prebiotics (Human Milk Oligosaccharides) for breastmilk-like nourishment.

Choose GMO-Free Products
