We believe breast milk is the best food for infants. When in consultation with their healthcare professional, mothers and families find that optimal breastfeeding is not possible due to their infant’s medical condition, formulas for special medical purposes play a vital role in providing essential nutrients to infants. We have a global commitment to market breast-milk substitutes responsibly.

SmilesBack App

What is the SmilesBack App?

Cows’ milk allergy (CMA) is a common food allergy in baby’s and young children but it is often challenging to diagnose and may take many months and doctors appointments. If you suspect that your baby might have cows’ milk allergy, you can use SmilesBack to help shorten the journey to diagnosis and help put smiles back where they belong.

SmilesBack is an easy-to-use app that has been developed with allergy experts and tested by parents. It enables you to easily track your baby’s symptoms and feeds and summarise them in a one-page, expert-designed report, to support your doctor before they make a diagnosis or to see if symptoms improve following any dietary changes.

IMPORTANT NOTICE: Breastfeeding is the best form of nutrition for babies and provides many benefits to babies and mothers. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breastmilk, and reversing the decision not to breastfeed is difficult. Always consult your healthcare professional for advice about feeding your baby. The social and financial implications of using infant formula should be considered. Improper use of an infant formula or inappropriate foods or feeding methods may present a health hazard. If you use infant formula, you should follow the manufacturer’s instructions for use carefully – failure to follow the instructions may make your baby ill. Formula for special medical purposes intended for infants must be used under medical supervision. SmilesBack and CoMiSS are not diagnostic tools. Always consult a healthcare professional if you have any concerns about your baby’s health. SmilesBack and ComiSS are not diagnostic tools.
