Sending your little one off to daycare? Brace yourself for a wave of illnesses—even in the summer. While you might think warmer months offer a reprieve, the start of a new school term can actually trigger a surge in sickness, thanks to the perfect storm of close contact and developing immune systems. But here's where it gets controversial: Is it better to expose kids early and build immunity, or shield them as long as possible?*
When children first enter group settings like daycare or preschool, they’re thrust into a world of shared toys, close interactions, and—unfortunately—germs. And this is the part most people miss: It’s not just about picking up viruses from surfaces; kids spread illnesses directly to each other through touch and play. Curtis Gregory, public health director at Illawarra Shoalhaven Local Health District, explains, “Children are highly interactive, constantly sharing objects and touching each other, which creates ample opportunities for viruses to spread.”
Their immune systems, still in the early stages of development, often struggle to fend off these new invaders. Gregory adds, “We call this ‘naive exposure.’ For instance, if a child encounters whooping cough for the first time, their immune system hasn’t learned to recognize or fight it yet. It’s a gradual process of building immunity.” Vaccines, he emphasizes, play a critical role by providing immediate protection and speeding up this process.
While winter is notorious for illness outbreaks due to indoor crowding and poor ventilation, summer has its own challenges. As schools reopen, kids reunite in classrooms and assemblies, reigniting the spread of germs. Gregory notes, “We often see a spike in illnesses like whooping cough and gastro at the start of new terms. Older kids bring these bugs home, exposing younger siblings, and the cycle continues.”
Here’s the frustrating truth: There’s no predictable timeline for when a child’s immunity will fully develop. Parents often feel trapped in a never-ending cycle of sickness, wondering when it will end. But Gregory reassures, “Over time, it does get better. Kids who attend playgroups or childcare tend to fare better in kindergarten because their immune systems have had more practice.”
In the meantime, focus on bolstering your child’s health with proper rest, a diet rich in fruits and vegetables, and plenty of hydration. Hygiene is equally crucial—though it’s no small feat with toddlers. Gregory advises, “Remind them to wash their hands before eating and after using the bathroom. You can’t sanitize every surface they touch, so prioritize high-risk moments like meal prep.”
But don’t let the frequency of these illnesses fool you—they’re not always minor. Gregory warns, “Symptoms can worsen quickly in young children. Trust your instincts and seek medical advice if you’re concerned. You’re not overreacting by being cautious.” For immediate guidance, he recommends HealthDirect’s 24/7 hotline at 1800 022 222, where nurses can provide tailored advice.
So, while summer might not shield your child from the daycare germ factory, understanding the ‘why’ behind the sickness can make it easier to navigate. Now, here’s a question for you: Should parents prioritize early exposure to build immunity, or is it better to delay group settings as long as possible?
