Why and How Natural Resistance Comes First
There are many elements that your child will be exposed to once they go outside the house. While they're mostly not dangerous, you need to ensure that your child has built enough natural resistance in order to lower the risk of catching something. After all, prevention is better than cure.
A child's ability to fend off infections is affected if there is an unbalance of bacteria. So you'll need to make sure your child has enough probiotics: a friendly bacteria that protects the digestive tracts, helps digest food, and assists in clearing toxin.
What you're not feeding your child is just as important as what you are. Keep additives, preservatives and sugar at a minimum. When your child has food allergy, it leads to poor digestion which makes fending off viruses and bacteria much more difficult.
If sleep-deprived, your child might get more susceptible to illness. So make sure your toddler take their naps during the day.
These small steps will potentially bring big benefits for your child's physical development. After all, the human body was never meant to be shielded from the sun all day every day. Just prepare your child's insides to embrace the world outside. He'll thank you for it some day.
