Yeah, this is why I’ll happily let my kids play in the ball pits etc. at malls. (provided they’re not visibly filthy ofc). Let them pick up the germs now so their bodies know how to fight it in the future. They’re 6 and 8 and rarely sick. My parents were massive germ-phobes and once I became a teen, minor sniffles at the school seemed to border on a medical emergency for me. Not to mention noro - the first time I got it was pure hell.
