Your toddler licking the playground equipment might actually be contributing to their microbiome…
And before anyone panics… I'm not recommending it. Unless that is just something your child loves to do. One of mine used to kiss the seeing eye dog statue. Looking back she must have always loved golden retrievers.
But children are constantly interacting with microbes in their environment.
🦮Pets
🪴Soil
🏀Parks
👥Other kids
🥝Food
All of these exposures help shape the gut microbiome.
Which means childhood is essentially one big microbial learning experience.
Their immune system and gut ecosystem are constantly figuring out how to interact with the world around them.
Messy play, outdoor time, and environmental exposure can actually be important parts of that process. Even if it occasionally makes parents cringe.
