During flu season, your baby becomes more susceptible to getting sick and catching it. First, it can be just a little cough or maybe fever, which doesn't seem like something serious at times, but being a mom and all, you can’t help but ask, “Is this something to be scared about?” During this time, it's important that you stay calm and know when to worry about flu in child. When you're calm, you can better detect warning signs and know the care that your baby needs at the time.
Cold and Flu Symptom in Babies

Babies under one year are more susceptible to viruses. Here are some common symptoms to look out for in babies:
- Fussiness or trouble sleeping
- Fewer wet diapers than usual
- Blocked or leaky nose
- Temp reading over 100.4°F
- Poor feeding or not interested in milk
- Sneezes and coughs that won’t quit
- Breathing that sounds heavy or includes small grunts
Small changes can mean big problems. Always be vigilant, and call your doctor if you notice serious symptoms like heavy breathing and trouble eating.
Cold and Flu Symptoms in Child

Flu symptoms in older children may be harder to notice and manage. Here are some signs you could look for:
- Sudden fever (High temp ones)
- Body aches or chills
- Headache or sore throat
- Leaky nose or cough
- Tiredness or low energy
- Nausea with vomiting or frequent watery poop
If their symptoms get worse faster, and they become sleepy, you should call someone for help.
Possible Causes of Cold And Flu Symptoms
It’s not always the viruses that cause the flu and cold symptoms. Here are some of the possible causes:
- Common cold (rhinovirus): Not that serious, symptoms are milder, and they are not that quick in terms of symptom progression.
- RSV (respiratory syncytial virus): Dangerous to infants, scary.
- COVID-19: it can mimic the symptoms of the flu.
- Allergies: symptoms always show coughing, a leaky nose, and consecutive sneezing
- Sinus infection: Persistent congestion or facial pressure, like a red nose
To ensure that it's not something serious, monitor the symptoms for about a week. If it got worse or still persists during that week of monitoring, call
Who’s Most At Risk?
Most of the time, healthy kids only need water and rest to get over the flu. However, there is still a chance of complications like pneumonia, ear infection, and dehydration.
Most at risk are:
- Babies under 6 months old
- Children with asthma or chronic illnesses
- Baby with a weak immune system
- Children who have neurological conditions
- Premature babies
- Those who haven’t received a flu shot.
At-risk children needs a faster and more focused care, as the progression of symptoms they experience may be more severe and serious. If your baby is included on the list, don't wait; act as soon as possible once the symptoms begin to show.
How Long Does Flu Last?
5-7 days is often the time it takes for Flu symptoms to come and go. Here’s what those 7 days may look like:
- Day 1-3: Sore throat paired with chills, muscle aches, and a rising temp
- Day 4-6: Low energy, tight chest, and a nose that just won’t clear up
- Day 7+: Symptoms may be gone or improving
Some children may get better in just a couple of days, while some can take weeks before feeling better. The 5-day monitoring is essential to see if your baby has something serious going on. If your baby didn’t show any signs of improvement on the first 5 days, you should consider seeing a doctor.
