Breastmilk is incredible – it offers a finish form of nutrition for infants, and offers a range of benefits for health, growth, immunity and development.

While being truly allergic or reacting to something in mom’s milk is rare in babies, a little percentage of mothers do notice a difference in their babies’ symptoms or behavior after eating certain foods.
So what counts as a food related reaction?
The most common signs of food allergy or intolerance in breastfed infants are eczema (a scaly, red skin rash) and bloody stool (with no other signs of illness). You might also see hives, wheezing, nasal congestion, vomiting or diarrhea.
If you notice any of these symptoms, an elimination diet can assist both to diagnose and treat a potential food allergy. This means removing potential allergens from your diet one at a time for weeks each while you continue breastfeeding and watching to see if your baby’s symptoms subside.

Babies can be unsettled for numerous reasons and it can sometimes take time and effort to work out the cause.
However it can be a genuine concern if your baby is uncomfortable, in pain, distressed or if he is being ill, experiencing diarrhoea or has other symptoms. The Unhappy Breastfed Baby can assist you determine whether your baby’s behaviour is due to something other than an allergy.
But when you own ruled out most of the obvious causes and your baby is still, unhappy, colicky or experiencing dry and itchy skin, you may start to wonder whether your breastfed baby could be reacting to something in his diet, environment, or, if he is exclusively breastfed, something in your own diet.
Certain medical conditions can own symptoms similar to those of an allergic reaction. It may be wise to law these out before deciding whether a baby’s symptoms are due to an allergy.
A food allergy occurs when a baby’s immune system creates specific antibodies to a specific food. If the baby is then given that food, his immune system releases chemicals including histamine that trigger inflammation and allergic symptoms. Symptoms can happen within minutes or up to several hours after eating the food responsible.
It’s wise to see your GP if your baby is showing signs of allergy, but some symptoms are more worrying than others. Seek medical assist quickly if your baby has an anaphylactic reaction: breathing difficulties, swelling, or a rash appearing immediately after physical contact or eating a specific food.
Cutting out suspect foods
If your baby is exclusively breastfed you may need to eliminate the suspect food from your own diet for a while.
Only cut out one or two foods at a time and permit 2–3 weeks to see if your baby improves. Be aware that symptoms sometimes get worse before they get better. If there is no improvement after this time then that food is unlikely to be the culprit and you can reintroduce it into your diet.
Work below the list (above) cutting out one food at a time. Start with cows’ milk, the most common cause of problems. Check package labels for milk products, which may be listed as: butter, yoghurt, cheese, whey, casein or caseinate, or lactose. These can turn up in the most unexpected foods and in some medicines and vitamin tablets.
Some milk-allergic children do well on goat or sheep milk, but these are comparatively rare—more generally a cows’-milk allergy predicts an equally severe allergy to other animal milks, although they can provide a temporary respite.
Some children who are allergic to milk also react to beef.
Find out as much as you can before you start an elimination diet and enquire your doctor for a referral to a dietician, especially if you need to cut out a major food group.
Unless your baby has experienced a severe reaction, you may discover you can reintroduce the offending food later in little amounts without causing symptoms. Seek medical assist if your baby has shown definite anaphylactic signs, such as an immediate rash, swelling or noisy breathing.

Identifying the problem food
If your baby is having only your milk

• Own you recently eaten a new food or any specific food in large amounts?
• Are there any foods that you don’t love but own decided to eat during pregnancy or breastfeeding because you ponder they will be excellent for you and your baby?
• Are there foods that you crave?
What foods do you snack on when you own a bad day?
• Do shut family members own problems with any specific foods? Depending on how sensitive your baby is, removing or cutting below on the offending items in your diet may well solve the problem.
If your baby is not fully breastfed
The majority of babies don’t need anything other than mother’s milk before about six months—no baby formula, drinks, solids or vitamins. Babies over six months who own started solids can be sensitive to certain common foods until they are a little older.
• Could your baby be reacting to the drinks or solid foods he is having?

• Could he be receiving other drinks such as baby formula or juice, or solid food, from anyone else without your knowledge?
Infant formula or follow-on formula is generally cows’ milk-based and a common, avoidable cause of allergy or intolerance.
Babies don’t need follow-on formula at all. Removing the offending food from your baby’s diet for now should solve the problem; he may be capable to tolerate it in a few months time. If you ponder your baby may be reacting to a prescribed medication that he has to take, speak to your doctor—he may be capable to prescribe an alternative.

• Cabbage, onions and spices.
Fenugreek is closely related to peanuts.
• Certain additives, artificial colourings, flavourings and preservatives.

• If a baby reacts when his mom drinks milk or has dairy products, this is a sensitivity to cows’ milk protein, not lactose intolerance.
• Most baby formulas contain cows’ milk, often referred to as ’whey based’ or ‘casein based’.
• Soya, the basis of some baby formulas, is also a common allergen.
• Baby formula may also contain fish oils and vegetable oils (eg palm, rapeseed, coconut, sunflower).

Doesn’t breastfeeding prevent allergy?
Breastfeeding generally helps to protect against allergy but it may still happen.
If one or both parents own an allergy or food intolerance, it makes it more likely that their baby will too. Early exposure to baby formula based on cows’ milk or soya increases the risk of allergy or intolerance both in childhood and in later life.
A baby’s immune system is immature at birth.
Colostrum, or early milk, is wealthy in antibodies, particularly sIgA, which provides a protective coating inside a baby’s intestines. Mature mother’s milk continues to provide protection, helping to prevent potential allergens from reaching a baby’s blood stream.
A food intolerance doesn’t involve an allergic reaction but can cause similar symptoms.
You may not need to stop giving your baby a food to which he is intolerant—reducing the quantity may be enough.
It can be fairly an effort to be an allergy detective with a fussy baby on your hands, so seek information and support. The excellent news is that little changes to your diet could make a large difference to a baby with a food allergy or intolerance. An LLL Leader can assist you determine the most likely cause of your baby’s symptoms.
