September is here: how to prepare your child's immunity for kindergarten

When dozens of children gather in one room, they exchange the viruses each of them brought from home. This is not an immunity failure but its training: according to paediatric data, young children catch on average 6 to 8 colds a year, and kindergarten children often more. Most of them pass mildly and on their own.

So the goal is not that the child never falls ill, but that illnesses are mild, rare and followed by quick recovery. This is where parental habits carry real weight, and the bottles of promises on the shelf do not.

The four pillars are boring but proven. Sleep: children aged 3 to 5 need 10-13 hours of sleep per day, and those aged 6 to 12 need 9-12 hours, according to the American Academy of Pediatrics; chronic sleep loss weakens the body's defences. Food: a varied table with fruit, vegetables and protein covers the needs without pills. Outdoor activity and handwashing - the cheapest daily vaccine against everyday viruses.

Vitamin D is the only one with an officially recognised role: it contributes to the normal function of the immune system, and in children it is needed for normal growth and bone development. In Bulgaria, autumn and winter sunshine is not enough for the body to make its own, which is why paediatricians widely recommend drops. The two verified drop forms are shown here and at the end of the article.

No syrup, drops or powder "for immunity" has been proven to protect a child from kindergarten viruses one hundred percent: such proof simply does not exist for any product. The evidence for echinacea, colostrum and most "immunomodulators" in children is weak and conflicting, and some of these products carry real risks - I covered this in detail in my article on herbal supplements in the Myth or Fact section.

Still, there is a nuance I see in pharmacy practice: supplements with vitamin C, zinc, vitamin D, beta-glucans or probiotic strains contribute to the normal function of the immune system, and many parents share that their children had a milder season, with rarer illness and quicker recovery. Products such as Regulatpro Kids, Defendyl and OMNi-BiOTiC Immund have a good composition and frequent positive feedback. The difference is in the expectation: they support immunity, but do not lock it and do not replace sleep, food and vaccines.

Watch the labels too: if a supplement promises to "protect from all viruses", that is an unlawful health claim. The claims allowed in the EU are strictly limited and sound far more modest.

Weeks before the first day: shift the child back to a kindergarten routine with an early bedtime, establish the "hands first, then breakfast" rule and provide vitamin D as recommended by the paediatrician. Check the vaccination calendar too: vaccines are the only thing with proven preventive power against specific diseases.

And the most important peace of mind: the first two to three months in a group almost always pass under the sign of a runny nose. But if the child has a high fever for more than 3 days, difficulty breathing, refuses food and fluids or is apathetic, that is a reason for the paediatrician, not for waiting.

The information in this article has been verified and is based on: the American Academy of Pediatrics recommendations on children's sleep duration, CDC guidance on hand hygiene for children, the EFSA register of authorised health claims for vitamin D and WHO guidance on physical activity for children.
