Should I Take My Child to the ER?

As a parent, few decisions feel more stressful than wondering whether your sick child needs urgent medical attention. Most parents know what to do in a clear emergency. But the more difficult question is often: “How do I know if this is an emergency?” Children can become unwell quickly, and sometimes a child who seems only mildly sick can deteriorate with little warning. To make things even more challenging, babies and toddlers can't always tell us how they're feeling. The good news is that there are some simple warning signs that can help you decide when your child needs urgent medical care. I often recommend parents use the 3Bs and 3Ps Quick Assessment Tool. It's a simple checklist that can help you quickly assess your child when they're unwell and identify red flags that shouldn't wait until morning. If your child shows any of the signs below, it's important to seek medical attention promptly.

The 3Bs: Key Signs to Watch For

1. Breathing

Breathing difficulty (your child having trouble breathing) is one of the most important warning signs in young children. Ask yourself:

• Are they working hard to breathe?
• Are they breathing faster than usual?
• Is their breathing noisy?
• Can you see their ribs sucking in with each breath?
• Are they struggling to talk, cry or feed because of their breathing?

If the answer is yes to any of these questions, your child should be assessed urgently.

Being able to assess breathing, work of breathing and difficulty breathing is something I want all parents to be able to do rapidly.

2. Behaviour

Parents know their child best. Changes in behaviour can be one of the earliest signs that something more serious is happening. Consider:

• Are they acting different to usual?
• Are they unusually sleepy or difficult to wake?
• Are they less responsive?
• Are they unusually irritable, floppy or lethargic?

A child who is difficult to rouse or not interacting normally should be seen by a healthcare professional as soon as possible.

3. Breast and Bottles

Hydration is critical, especially for babies and toddlers. Pay close attention to what your child is drinking. Ask yourself:

• Are they taking less than half of their usual fluids?
• Are they refusing breastfeeds, formula, water or oral rehydration fluids?
• Have they stopped drinking altogether?

Children can become dehydrated quickly, particularly when they have fever, vomiting or diarrhoea. Drinking less than 50% of their usual intake is a significant warning sign, as is output (through urine, sweat, vomit or diarrhoea) being higher than intake (drinking).

Poor feeding can quickly lead to dehydration in babies; see my blog here for more.

The 3Ps: Red Flags to monitor

1. Pee

Urine output provides valuable clues about hydration and overall health. Watch for:

• Fewer wet nappies than usual
• Long periods without urinating
• Dark yellow urine
• Strong-smelling urine

A noticeable decrease in urine output can indicate dehydration and warrants medical review.

2. Poo and Vomit

The colour of your child's vomit or bowel motions can sometimes signal a serious problem. A simple rule to remember is: If you see red, white or black; get it checked. These colours can sometimes indicate bleeding, or liver or bowel problems, and should be assessed promptly by a healthcare professional.

3. Pain

Pain is another important warning sign, particularly when it is severe, persistent or worsening. Seek medical attention if your child has:

• Increasing pain that isn't settling
• Persistent pain that keeps returning
• Eye pain
• Headaches that worsen in bright light (photophobia)
• Pain associated with fever
• Pain combined with breathing difficulties

Children may not always be able to explain their pain clearly, so trust your instincts if something doesn't seem right.

Trust Your Gut

While the 3Bs and 3Ps provide a helpful framework, there is another important tool that should never be ignored: parental instinct. If you feel that your child is significantly unwell, even if you can't quite explain why, it's always worth seeking medical advice. You know your child better than anyone else.

When to Go to the Emergency Department

If your child has any of the warning signs listed above, particularly problems with breathing, unusual drowsiness, poor fluid intake, signs of dehydration, concerning vomit or stools, or significant pain, they should be assessed urgently. It's always better to have a child checked and be reassured than to delay care when something serious may be developing. When in doubt, seek medical attention.

The Bottom Line

The 3Bs and 3Ps offer a simple, practical way to assess your child when they're unwell: 3Bs

• Breathing
• Behaviour
• Breast and Bottles

3Ps

• Pee
• Poo and Vomit
• Pain

If any of these areas raise concerns, don't wait. Seek medical advice or attend your nearest emergency department. Because when it comes to children's health, early assessment can make all the difference.

An Important Extra Warning Sign: Non-Blanching Rash

While the 3Bs and 3Ps are a helpful framework for assessing an unwell child, there is one important symptom that deserves special mention: a non-blanching rash. A non-blanching rash is a rash that does not turn white or fade when you press on it.

You can test this by pressing a clear glass firmly against the rash or applying gentle pressure with your finger. If the spots remain visible and do not blanch, this is very serious and needs immediate medical attention.

If you're ever unsure whether a rash is blanching or non-blanching, seek medical advice promptly.

A Note About Childhood Illnesses and Medications

Most childhood illnesses are mild and improve with supportive care. However, some conditions can progress rapidly and require urgent assessment. Importantly, children’s aspirin should generally not be given to children unless specifically recommended by a doctor, as it can be associated with serious complications.

Trust Your Instincts

No assessment tool replaces parental intuition. If your child’s symptoms concern you, or you feel they are significantly unwell, seek medical advice promptly. You know your child best, and early assessment can make all the difference.
