Babies are born with incredible resilience, but their developing immune systems make them more susceptible to common illnesses, especially during the first year of life. As a parent or caregiver, it’s natural to feel a bit anxious when your baby shows signs of being unwell. The good news is that most infant illnesses are mild and manageable at home with proper care and attention.
Knowing how to recognize the symptoms, understand what’s normal, and when to call the doctor can give you confidence and peace of mind as you care for your little one.
Let’s take a look at some of the most common infant illnesses, their symptoms, and helpful ways to treat them.
🤒 1. The Common Cold
What to look for:
- Use a bulb syringe or nasal aspirator to clear mucus.
- Run a cool-mist humidifier in the baby’s room to ease congestion.
- Offer plenty of fluids (breast milk or formula).

📝 Note: Colds usually last 7–10 days. Call your pediatrician if symptoms worsen or the baby develops a high fever.

What to look for:

What to look for:
- Rectal temperature of 100.4°F (38°C) or higher
