Starting daycare is a big milestone—for your child and for you. Whether you’re excited, nervous, or fighting back a few tears at drop-off, know this: You’re not alone, and what your child is going through is completely normal. Here’s what pediatricians say you can expect in those first few weeks—plus how to support your child’s immune system as they adjust to their new environment.
1. Expect a Few Sick Days (Or… a Lot)
No matter how clean your daycare is, germs come with the territory. In fact, most kids will have 8 to 12 colds during their first year in a group care setting.
“It’s completely normal for young children to get sick more often when they first start daycare,” said Dr. Marcy Solomon Baker, pediatrician and medical director of BayCare Medical Group Pediatrics. “They’re building their immune system by being exposed to new viruses.”
The first few months of daycare often come with runny noses, coughs and the dreaded stomach bugs. It's not just your kid—everyone goes through it.
Common daycare illnesses include:
It might feel like your child is constantly sick at first—but most bounce back quickly and build stronger immunity over time.
2. The Best Way to Build Immunity Is… Slowly and Naturally
You can’t supercharge your child’s immune system overnight. But you can help strengthen it with everyday healthy habits.
“There’s no magic medicine that builds the immune system—it develops over time,” explained Dr. Baker. “Vaccines, good nutrition, regular sleep and low stress all help it grow strong.”
She adds that picky eating, irregular sleep schedules and high stress can weaken immune response—especially in young children and teens.
“Sometimes we think it’s a cliché to say kids need sleep or a balanced diet, but it’s absolutely true. But even kids who have strong immune systems commonly get sick when they start daycare,” said Dr. Baker.
Here’s how to support your child’s immunity:
3. Yes, Separation Anxiety Is Normal
Don’t be surprised if your child cries—or clings onto you—during the first few drop-offs. This transition is a big deal for little ones, but rest assured—it gets easier.
“Young children thrive on routine,” said Dr. Baker. “The more consistent your goodbye and daily schedule, the faster they’ll adjust.”
Try to keep drop-offs short, sweet and confident—even if you’re faking it.
4. You May See a Lot of Big Emotions at Home
After a full day of socializing, sharing toys and trying new things, don’t be shocked if your child melts down the second they get in the car.
“It’s not uncommon for toddlers to have meltdowns after daycare,” said Dr. Baker. “They’ve held it together all day, and home is where they feel safe enough to release that energy.” Offer cuddles, quiet time and an early bedtime to help them recharge.
5. They’re Growing in More Ways Than One
Yes, they may be getting sick more, but your child is also learning social and emotional skills that will last a lifetime.
“Play-based learning in daycare helps children develop language, empathy and confidence,” added Dr. Baker.
So those messy finger-paint masterpieces? They're helping your child’s brain and immune system grow.
Daycare is full of firsts: first friends, first runny nose, first meltdown—and first big step toward independence. With expert support and a few extra boxes of tissues, you’ll both make it through stronger than ever.
