Um I’m going to give a way better answer than them^^ Because children immune systems are not as strong as adults or young adults their cells can’t fight sickness or viruses or diseases as good as someone older so if they were sick we try to get them assisted quickly because their so fragile and it’s life or death
When a kid comes into a Emergency room / office they are the ones that get checked immediately depending on what there cause is. Here is why, kids health system is still growing. If anything were to get infected or in the way of it growing it could cause serious injury. Kids are still developing and need more attention, adults can handle more stuff since there system is more advanced.
