    Family history can increase the risk of developing allergies such as asthma in babies


    Breastfeeding is the best way to help prevent allergies including eczema in babies


    For babies at risk of allergies that aren’t breastfed, ask your GP or healthcare professional about specific hydrolysed formulas that have been clinically proven to reduce the risk of developing allergies

    The good news is that most little ones will grow out of baby allergies in childhood

    The number of people with hayfever, food allergies, eczema and asthma are all on the up. According to Allergy UK, a leading national allergy charity, half of all children in Britain are now affected by allergies, and one in five children are reported to develop eczema, with the highest incidence being in the first 12 months of their life. This is surprising stuff, but what causes allergies, and is there anything we can do to reduce their risk?

    Symptoms of baby allergies

    Having an allergy means your body overreacts to a normally harmless substance. It sees allergens like pollen or food as threats and produces antibodies to fight them. This results in an allergic reaction and baby allergy symptoms, including:

    • Sneezing
    • A runny or blocked nose
    • Red, itchy and watery eyes
    • Wheezing and coughing
    • A red and itchy rash
    • Worsening of asthma or eczema

    Most reactions are mild and, although annoying, can be largely kept under control. But severe reactions, such as breathing difficulties or anaphylaxis can occasionally happen – these need immediate medical attention.


    Are allergies inherited?

    Chances of conditions such as eczema in babies increase if family members have a history of allergy. Even if one member has asthma or hayfever, there is a 20-40% chance of a baby developing an allergy. If both parents — or one parent and a sibling — have allergies, that risk rises to 60-80%. Some of these allergies will go away as a child gets older, although many are lifelong.

    How to reduce the risk of your baby developing allergies

    Breastfeeding is the best protection you can offer your baby against allergies. Studies show that infants exclusively breastfed for at least their first six months are less likely to develop eczema compared to babies fed formula milk containing cows’ milk protein.

    • Breastfeeding reduces your baby’s exposure to allergens from food sources found in cows’ milk based formula, as well as certain weaning foods
    • Breast milk contains antibodies that help support your baby’s immature immune system to fight allergic reactions
    • Breast milk is also a good source of omega-3 fatty acids which helps with the development of the immune system and prevents allergies from developing

    But when exclusive breastfeeding isn’t possible, for whatever reasons, there are specific hydrolysed formulas that are clinically proven to reduce the risk of developing allergies:

    • The protein in these hydrolysed formulas is treated and so lessens the chance of the immune system reacting to the protein
    • Always speak to your healthcare professional or pharmacist for advice on which formula is best for your baby

    Is my baby at risk, or just a fussy eater?

    Your baby can’t yet tell you what’s bothering them. But learning the difference between food allergies, intolerances and fussy eating can help you figure out if something’s wrong with your baby or your cooking. Find out how to deal with fussy eating and food allergies and intolerances.

    IMPORTANT NOTICE: The best way to feed a baby is to breastfeed, as breast milk provides the ideal balanced diet and protection against illness for your baby and also has many non-nutritional benefits for both baby and mother. We recommend that you speak to your healthcare professional when deciding on your choice of feeding your baby. Professional guidance should also be sought on the preparation for and maintenance of breastfeeding. If you do choose to breastfeed, it's important to eat a healthy, balanced diet. Infant formula is intended to replace breast milk when mothers choose not to breastfeed or if for some reason they are unable to do so. A decision not to breastfeed, or to introduce partial bottle-feeding, will reduce the supply of breast milk. If for any reason you choose not to breastfeed, do remember that such a decision can be difficult to reverse. Using infant formula also has social and financial implications which must be considered. Infant formula should always be prepared, used and stored as instructed on the label, in order to avoid risks to a baby’s health.
