Baby Steps For The Immune System
volume 18, pages 600601
Early-life exposures are known to be crucial for shaping the developing immune system but the processes involved are poorly understood. Petter Brodin and colleagues have performed longitudinal immune profiling of blood from newborn infants and report that the individual immune phenotypes seen at birth are highly diverse however, infant immune systems then seem to converge on a shared developmental pathway in the first few weeks after birth, despite differences in environmental exposures. They propose a model of stereotypic immune system development, in which the exposure of infants to many diverse environmental stimuli after birth leads to the convergence of initially diverse immune systems.

Tip #: Start During Pregnancy
We now know the lifestyle and diets of both women and men impact the health of their unborn babies.
In fact, recent research has shown what you eat during pregnancy can impact three generations. Yeah I know, no pressure, right?!
It was always thought that at birth, babies had a sterile gastrointestinal tract colonised with microflora, starting at birth from exposure to mums skin and genitourinary tract.
But from looking at samples of umbilical cord blood and babies first bowel movements, researchers found that babies already exhibited some gut bacteria. The researchers believe babies acquire this from the mothers digestive system during pregnancy.
Since the bacteria strains identified can be affected by diet and lifestyle, eating well and staying healthy during pregnancy can be the first step you take in helping your babys immune system develop.
Aim to eat a variety of fresh, nutritious foods and limit the amount of processed foods you consume, which can wreak havoc on your immune system. Avoid or cut out sugar and processed grains . Increase your intake of good fats if you dont consume much. Avocado, coconut oil, chia seeds, fish, eggs, nuts and seeds are all fantastic for your body and immune system.
Make sure you eat enough protein, especially for breakfast , vegetables, leafy greens, good fats, nuts and seeds. Keep fruit minimal one small to average sized serve per day.
There are many benefits to a healthy lifestyle before you conceive and during pregnancy.
Your Babys Vulnerability To Viruses
Keep in mind that new babies are vulnerable to viruses. Here are some of the most common to watch out for:
- Stomach virus. Gastrointestinal viruses can present significant problems for infants, Dr. Sabella says. They can cause dehydration resulting from diarrhea. These bugs also can quickly spread to the bloodstream if they strike during a babys first month of life. That kind of infection can cause liver damage, meningitis, encephalitis and heart inflammation.
- Respiratory syncytial virus . Infants under six months of age who get this virus are often hospitalized. It can cause bronchiolitis, a condition where the small airways in the lungs swell block air flow and fill with mucus. RSV also causes pneumonia.
- Flu. Infants get sicker with the flu than older children and adults do. Although there is potential treatment of the flu virus, it often can turn into pneumonia or apnea, Dr. Sabella says.

Breast Milk From Obese Mothers And Their Effects In Newborn Immunity
Breast milk from obese mothers displays a proinflammatory profile and contributes to neurodevelopmental alterations in the newborn. Reports confirm that maternal body mass index correlates with higher omega-6 to omega-3 fatty acid ratio and lower concentrations of lutein and docosahexaenoic, eicosapentaenoic, and docosapentaenoic acids in the breast milk . The authors confirm that concentrations of saturated fatty acids and monounsaturated fatty acids in breast milk were positively associated with maternal inflammation . In fact, breast milk from obese mothers is positively associated with a pro-inflammatory profile , suggesting that obesity contributes to breast milk composition and susceptibility to negative outcomes in the newborn.

Tip #: Avoid Antibiotics If Possible
Antibiotics, like formula, change the balance in the gut.
While theyre great for healing an infection, they can wreak damage when overused.
A common reason for early antibiotic use is when a pregnant women tests positive to Group B Strep. If you test positive for Group B Strep, or if you want to be prepared, make sure you read our article, here.
One study, for example, found links between antibiotic use in the first year and asthma during adolescence and bowel problems during childhood.
If your baby does need antibiotic treatment for an illness, you might want to consider using probiotics to build beneficial gut bacteria. Speak to your naturopath to source a great quality probiotic designed especially for babies.
With all you will do to keep your new baby healthy, these simple steps may be the foundation for building a strong immune system for life.
Features Of The Neonatal Immune System
Pattern recognition: Neonatal responses to pathogen associated molecular patterns are reduced compared to adults. However pattern recognition receptor -expression levels are similar. It appears that the molecules that transduce the signal have reduced function. This leads to reduced production of key inflammatory mediators, for example interleukin-12 and interferon- . PRR function increases over time, and the increase in capacity occurs in proportion to time since birth rather than gestational age, suggesting that it is controlled by exposure to the environment and removal of maternal influence.
T-cell response: There is a well-documented skewing of the neonatal T-cell response towards T helper 2 . This is associated with the reduction in IL-12 and IFN production by neonatal antigen-presenting cells . This may have an effect on the immune response to antigens seen in early life possibly inducing an allergic type response.
B-cell response: Antibody production in early life is reduced. In particular the antibody response to polysaccharide antigens is reduced. This is a particular problem with regards to bacterial infections, to which newborn children are highly susceptible. This failure to produce antibody is associated with several factors including reduced T cell help, fewer follicular dendritic cells and germinal centres and reduced signalling through the CD40 ligand family members.

Transfer Of Protection From Mother
The main component of immune protection transferred from mother to child is antibody. This is transferred across the placenta to the foetus using the FcRn . Antibody is also transferred to the infant via breast milk. The main immunoglobulin class transferred is IgA, the transferred IgA works at mucosal surfaces, where it is able to prevent pathogen entry. However other important factors are transferred, including complement and commensal bacteria which may provide protection against asthma and allergy in later life .

How To Boost Kids Immune System
1. Avoid antibiotics unless absolutely necessary
Antibiotics are prescribed more than 154 million times a year for anything from a wound to an ear infection. The purpose of antibiotics is to kill off bacteria causing infections, and sometimes they are lifesaving, for sure. However, the CDC estimates that at least 30 percent of antibiotic prescriptions are unnecessary. This matters because antibiotics not only wipe out pathogenic bacteria, but deplete the beneficial bacteria in the gut microbiome. Why kill off the good guys when its not necessary?
If a doctor prescribes your child antibiotics, dont just accept the prescription without a few questions. How necessary are these antibiotics? How likely is it that your childs natural immunity will take care of the problem without the medicine? Are there more natural anti-bacterial options? Doctors focused on natural health sometimes recommend alternatives such as colloidal silver over antibiotics, to boost immunity without depleting the microbiome.
2. Serve more probiotic-rich foods
3. Regulate the family sleep schedule before the first day of school
4. Out with the sugar, in with the fruit
5. Give them a colostrum boost
6. Show them the door
7. Green up your meals
8. Experiment with essential oils

Tip #: Maximise Your Chances Of Having A Vaginal Birth
The way you give birth can make a difference to babys developing immune system. Babies born by cesarean section are colonised with different types of bacteria than those born vaginally.
For example, one study found higher levels of C. difficile which is an infection that can cause diarrhoea and intestinal problems in babies born by c-section. In the same study, babies born vaginally had low C. difficile rates, but higher bifidobacteria levels.
Bifidobacteria is essential for proper gut function, a friendly bacteria that promotes health. You can reduce your risk of a c-section by staying active and eating well in pregnancy, avoiding early induction, using natural methods for pain relief during labour, and having an active labour.
For many years, studies have consistently found that a doula can significantly reduce your chances of a c-section, without doing any harm. Recent research published in the American Journal of Managed Care found c-sections could be reduced by 60-80% where a doula was present at birth.
Not only are those figures gob-smacking, but it just goes to show how many unnecessary c-sections are being performed when a non-medical, but trained birth support person can make such a massive impact on surgery rates. You can read more here.

Give Them A Healthy Diet
By “healthy” I mean a diet with lots of fruits and vegetables , whole grains, and lean protein. A healthy diet also has dairy or another source of calcium, and healthy fats, like vegetable oils.
The foods to avoid are processed foods, foods with added sugar, and foods with unhealthy fats, like the saturated fats found in animal products. That doesnt mean your child cant ever eat cookies or ice cream. But if you want to your child to be healthy, they shouldnt eat those foods every day. .
There are many supplements that claim to boost your immune system. While the jury is still out as to whether most of them make a real difference, none of them take the place of a healthy diet. If you have a child who refuses vegetables or otherwise has a limited diet, a multivitamin with iron may make sense talk to your doctor about whether vitamins or supplements are a good idea for your child.
Prioritizing Breastfeeding For Healthy Newborn Maturation
Maternal breastfeeding has been practiced over millennia to secure good nutritional status for newborns . Breast milk is an extraordinarily complex, highly variable bioactive fluid, with changes in composition depending on the stage of lactation , time of day, and physiological/nutritional state of the woman. Obstetric practices during labor play a critical role in initiation of effective breast feeding. For example, labor induced with oxytocin was negatively associated with effective breastfeeding initiation 36 h after birth, suggesting that induction of labor with oxytocin should be used judiciously . In fact, the World Health Organization and the United Nations Children’s Fund recommend starting breastfeeding no later than 1 h after birth and that infants should be feed exclusively with breast milk for at least the first 6 months of life, and that breastfeeding should continue, supplemented with solid foods, until 2 years of age or longer . Breastfeeding for the first 6 months of the life of an infant has enormous long-term health benefits, including prevention of the risk of metabolic-related comorbidities such as overweight and obesity, type 2 diabetes , and chronic diseases in the infant . Breastfeeding also improves positive metabolic outcomes in mothers .
