Your child is sick, it is after hours or the weekend, and you are staring at three choices: the pediatrician’s office, an urgent care clinic, or the emergency room. Picking the right one saves time, money, and worry — and in a true emergency, it can save a life. At Immediate Care Center of Westmont, our walk-in clinic in Westmont, IL helps DuPage County families make this call every day. This guide breaks down what each option is best for, so you can decide with confidence when your child needs care.
We serve families across Downers Grove, Hinsdale, Oak Brook, Darien, Clarendon Hills, Willowbrook, La Grange, and Villa Park, with an on-site lab and digital X-ray to handle many childhood illnesses and minor injuries in a single visit.

Your child’s pediatrician or primary care provider knows your child’s history, growth, allergies, and vaccination record. This is the best first stop for:
The tradeoff is availability. Pediatric offices are usually closed evenings, weekends, and holidays, and same-day appointments can be scarce during busy seasons. For newborns and very young infants, though, always start by calling your pediatrician — especially for a fever, which in a baby under 3 months is an emergency (more on that below). If your family does not have a regular provider, our clinic also offers primary care services.
A walk-in urgent care like ours fills the gap when your child needs prompt attention but is not facing a life-threatening emergency, and the pediatrician is closed or booked. Our pediatric urgent care is a strong choice for:
The advantages are real: no appointment needed, extended and weekend hours, shorter waits than a typical ER, and generally lower out-of-pocket cost than an emergency room for the same non-emergency problem. Because we have an on-site lab (strep, flu, RSV, UTI, bloodwork) and digital X-ray, we can often diagnose and begin treatment during one walk-in visit. For details on what your visit may involve, see our cost and insurance page or call us — we never guess at your specific costs over a blog post, but our team can help you understand your options.
The ER is built for serious, potentially life-threatening emergencies and has resources urgent care and pediatric offices do not, including advanced imaging, specialists, and the ability to admit a child to the hospital. Go to the ER, or call 911, for the situations in the callout below.
Call 911 or go to the nearest emergency room right away for:
When a child’s life or a limb may be at risk, do not spend time deciding — call 911. Urgent care is not equipped for these true emergencies, and we will always send a critically ill or injured child to the ER without delay.
When you are unsure, ask yourself three questions:
And remember, the pediatrician remains the best home for routine and ongoing care whenever the office is open.

For any infant under 3 months old with a temperature of 100.4°F (38°C) or higher, do not wait and do not give fever medicine. Call your pediatrician immediately or go to the nearest emergency room. Young babies with fever often need hospital-based testing that urgent care cannot provide.
Real life rarely comes with a label, so it helps to see how everyday situations typically map to each option. These are general guides, not rules — when in doubt, escalate.
Notice the pattern: urgent care handles the broad middle of prompt, non-emergency needs, the pediatrician anchors routine and ongoing care, and the ER is reserved for the genuinely serious. Matching the problem to the right setting spares your family unnecessary waits and expense while making sure a real emergency gets the resources it demands.
Whichever option you choose, a little preparation speeds things along and improves your child’s care. Try to bring or have ready:
For non-emergency visits to our walk-in clinic, you can also check in online before you arrive, which helps reduce your time in the waiting room.
For the same non-emergency problem, urgent care generally costs less out of pocket than an emergency room visit, though your exact cost depends on your insurance. We cannot quote a specific price in an article, but our cost and insurance page and our front desk can help you understand your coverage. For a true emergency, cost should never delay care — go to the ER.
