1. Too zealously trying to protect them from infections by restricting their contacts, distancing them from other children when they play, and washing everything with disinfectants. These measures hinder the normal development of the immune system, which can lead to lowering immune response and developing severe forms of diseases under the influence of infection (viruses, bacteria, or fungi). 2. Giving them a hypoallergenic diet in the absence of medical symptoms, in an attempt to protect them from an allergy. Having a less diverse diet increases the risks of developing allergies and leads to nutrient deficits (vitamins, microelements, amino acids). 3. Giving them a diet that is too diverse for them — for example, exotic fruits. If foods are introduced before the child is developed enough to try them, it can lead to allergy and digestion problems. 4. Trying to avoid hypothermia by making them wear too many clothes. Experience with a mild cold can help children develop normal thermal regulation. 5. Self-medicating children because we don't trust doctors or friendly advice. Obviously, caring adults spare no expense for the best medicines for their children, but in doing so they should consult with experts on the specifics of children's bodies. Many medicines and food additives pose serious harm to children’s health. 6. Trying to give our children the most diverse education and driving them by car so that they can participate in everything. As a rule, all classes, including sports classes (especially in big cities), are run indoors. Children need to spend time outside, as not being outdoors leads to a low level of oxygen and deficiency in vitamin D. 7. Indulging children with smartphones, tablets, and laptops. Typically, children like spending their time with gadgets, especially if they don't have adults or friends around who are ready to spend time and play with them. However, obsession with computer games leads to hypodynamia, impaired social behavior, increased irritability, and sleep disorders. 8. Wishing that our children start studying as early as possible to achieve more than we did. Early childhood development should be assisted by experienced tutors. The abilities to play, imagine, and organize their playground are essential skills for a child’s future. Skipping games for studies too early interferes with the all-around development of the child. 9. Shielding children from chores. A 2–3-year-old child can already help with cleaning up, and this is the best age to start asking children for assistance. Feeling involved in family activities boosts self-confidence and develops a feeling of responsibility. 10. Keeping children away from animals for fear of allergies. Research has shown that, in most cases, early contact with animals decreases the risk of developing pet-related allergies.
