The twins recently turned two, and I’ve realized we've experienced what feels like every common childhood illness imaginable.
Hand, foot, and mouth disease. Roseola. The flu. COVID. Ear infections. Countless mystery viruses that started with a high fever and left me wondering what was coming next.
As I write this, we're actually going through our second round of hand, foot, and mouth disease. It has me reflecting on how differently I'm handling it this time compared to the first time.
What a difference two years of parenting can make.
If you've been following along with Mama Poe's Posts, you know I struggled with postpartum anxiety after the twins were born. Every fever felt terrifying. Every new symptom convinced me something serious was wrong. I spent countless nights searching Google while everyone else slept. I actually even questioned if they had cancer on multiple occasions (thank GOD for SSRI's).
Now?
I'm still cautious, but I've learned that childhood illnesses are, unfortunately, just part of raising babies and toddlers.
I wish the hospital had sent us home with a handbook titled "Everything Your Baby or Toddler Is Probably Going to Catch During the First Few Years."
Because while they teach you how to swaddle a newborn and buckle a car seat, no one really prepares you for the endless parade of viruses that seem to appear out of nowhere.
If you're currently holding a feverish baby or toddler, I hope this guide gives you a little reassurance.
Toddler Fever Is Usually Caused by a Virus
One of the biggest surprises for me as a first-time mom was learning how often babies and toddlers develop high fevers from completely routine viral illnesses.
A high fever doesn't automatically mean your child has a serious infection.
In fact, many common childhood illnesses begin with nothing more than a fever before any other symptoms appear.
Some of the illnesses we've experienced include:
Hand, foot, and mouth disease
Roseola
Influenza (the flu)
COVID
Common colds
Ear infections
Other viral illnesses that never even received a name
Sometimes the fever is the very first symptom. The rash, cough, congestion, sore throat, or mouth sores don't show up until a day or two later.
Keep Your Expectations Extremely Low
This is probably the biggest lesson I've learned.
Like, take what you think low expectations means and go even lower than that.
When your child is sick, your goal isn't to maintain your normal routine.
Your goal is to help them feel safe, comfortable, hydrated, and loved.
The laundry can wait.
The dishes can wait.
The house can be messy.
The screen time rules can relax.
Sometimes success simply looks like everyone making it through the day.
Don't Stress About Your Schedule
This one was really tough for me to learn. We normally thrive on routines, and I take independent sleep pretty seriously.
Our family has predictable nap times, bedtimes, and meal schedules because they genuinely make life easier.
But sickness changes everything.
Your baby may suddenly want to be held all day.
Your toddler who normally sleeps independently may only nap on your chest.
Bedtime might happen early.
Naps might be longer.
Everyone may spend the afternoon cuddled on the couch watching movies.
That's okay.
Children often need extra comfort when they're sick. A few days of extra snuggles will not erase months of healthy sleep habits.
Once they feel better, your normal routine usually returns surprisingly quickly.
Fed Is Best...Especially During Illness
One thing I've stopped worrying about?
Perfect nutrition during a stomach bug, sore throat, or viral illness.
If my child only wants popsicles for two days...
They get popsicles.
If they'll only eat applesauce, yogurt, pudding, smoothies, crackers, toast, or ice cream because swallowing hurts...
That's okay too.
Hydration is often much more important than balanced meals during a short illness.
Once they recover, their appetite almost always comes back.
Common Childhood Illnesses That Cause Fever
Although every illness is different, these are some of the most common reasons babies and toddlers develop fevers:
Hand, foot, and mouth disease
Roseola
Influenza
COVID
Ear infections
Respiratory viruses
Strep throat (more common in older toddlers and children)
Viral upper respiratory infections
Many of these illnesses begin with fever before other symptoms develop, which is why the first day can feel especially scary.
How to Keep a Sick Baby or Toddler Comfortable
While every illness is different, these simple comforts have helped us through countless sick days:
Offer fluids frequently to prevent dehydration.
Let your child rest as much as they want.
Dress them in lightweight, comfortable clothing.
Use fever-reducing medication if recommended by your pediatrician.
Offer soft, cold foods if their throat or mouth hurts.
Don't force meals if they aren't interested in eating.
Give yourself permission to slow down and simply care for your child.
Sometimes the best medicine isn't another gadget or parenting hack.
Sometimes it's just sitting on the couch together.
When Should You Call Your Pediatrician About a Fever?
While most fevers are caused by common viral illnesses, there are times when your child should be evaluated by a healthcare provider.
Contact your pediatrician if:
Your baby is younger than 3 months and has a fever.
Your child has trouble breathing.
They are difficult to wake or unusually difficult to comfort.
They show signs of dehydration, such as very few wet diapers, dry mouth, or no tears when crying.
The fever lasts several days or keeps returning after improving (*Roseola and Hand foot and Mouth usually have 3-5 days of high fevers with no other symptoms until the rash appears).
Your parental instinct tells you something isn't right.
You know your child better than anyone else. Never hesitate to call your pediatrician if you're concerned.
You're Doing Better Than You Think
If you're reading this while your baby or toddler has a fever, take a deep breath.
You don't need to be the perfect parent today.
Lower your expectations.
Cancel your plans.
Contact nap if that's what your child needs.
Say yes to the popsicles.
Order takeout.
Hold them close while they lose their cool. They're scared and don't know why they feel the way the do.
Watch another episode of Bluey.
The routines, vegetables, independent sleep, and perfectly clean house will still be there next week.
Right now, your child doesn't need perfection.
They just need you.
And from one mom who's survived more childhood illnesses than she can count—you've got this.
