When to Worry About a Toddler’s Fever
Toddler Fever: What Ontario Parents Need to Know
When your toddler feels hot and cranky, that first instinct is to reach for the thermometer with worried hands. The good news? Most fevers in toddlers aren't dangerous, even when they climb higher than you'd expect. Your little one's body is just doing its job, fighting off whatever bug came home from daycare.
What's going on?
A fever means your toddler's immune system has kicked into high gear. Their body temperature rises to help fight off viruses or bacteria more effectively. It's actually a sign that their immune system is working well, not that something is terribly wrong.
Most childhood fevers come from common viruses like colds or stomach bugs. These usually run their course in a few days, with the fever being just one part of the process. Toddlers tend to run higher fevers than adults because their immune systems are still learning and sometimes overreact a bit.
The number on the thermometer matters less than how your child looks and acts. A toddler with a 102°F fever who's still playing and drinking might be doing better than one with a 100°F fever who's very listless.
What you might notice
- Temperature of 100.4°F (38°C) or higher
- Warm or flushed skin
- Less energy than usual
- Fussiness or clinginess
- Not wanting to eat or drink as much
- Sleeping more than normal
What helps at home
Focus on keeping your toddler comfortable rather than obsessing over the exact temperature. Dress them in light, breathable clothing and keep the room at a comfortable temperature.
Give plenty of fluids like water, milk, or diluted juice to prevent dehydration. Popsicles and ice chips work great too if they're being picky. Let them rest as much as they want, even if it means extra screen time or snuggles.
You can give children's acetaminophen or ibuprofen following the package directions for their weight. Don't give both at the same time unless your healthcare provider says it's okay.
When to worry
Head to the emergency room if your toddler has trouble breathing, won't wake up properly, has a stiff neck, or develops a rash that doesn't fade when you press on it.
Call your doctor or text Arlo if the fever lasts more than three days, your toddler isn't drinking fluids, seems very unwell, or if you're just feeling worried. Trust your parent instincts. You know your child better than anyone, and if something feels off, it's always okay to check in with a healthcare provider.
The takeaway
Most toddler fevers are just part of growing up and building immunity. You're doing great by staying calm and keeping them comfortable.
You can always text Arlo and talk to a provider in 5 minutes!
