How to tell if your child is sick

How can I tell if my child is sick?

The best guide to your child’s state of health is their behaviour. If they are happy and active and if they are playing and eating as they usually do, they are probably not very sick.

A sick child may:

• be unsettled or irritable
• lose interest in playing or be unusually quiet and inactive
• not want to eat
• feel hot to touch
• look tired, flushed or pale
• shiver or complain of feeling cold

What symptoms should I look out for?

Drowsiness

If your child is feeling sick, they may be sleepy and not interested in playing. However, you should take them to the doctor straight away if:

• they seem very drowsy and don’t wake up easily
• they don’t have enough energy to cry loudly
• they seem floppy when you pick them up

Breathing changes

If you notice any changes in your child’s breathing, take them to the doctor straight away. You might notice:

• fast or noisy breathing
• grunting sounds with each breath
• the skin between their ribs sucking in with each breath

Dehydration

Dehydration is when your child doesn’t have enough fluid in their body. If your child has a fever or doesn’t want to drink, or if they are losing fluid through vomiting or diarrhoea, they could become dehydrated.

If your child is drinking less than half their usual amount, or if they are passing less urine than usual, they could be dehydrated and should see a doctor.

Other symptoms

A child who is feeling sick may also have:

• vomiting
• diarrhoea
• pain
• a cough
• low appetite
• tiredness
• pale skin or a rash

How do I check my child’s temperature?

Checking body temperature by feeling your child’s forehead is not reliable. Always use a thermometer.

There are different types of thermometers and the results may vary depending on what you use. Good options are:

• a digital or mercury thermometer, which is placed under the tongue or in the armpit. Don’t place it under the tongue in children younger than 4 years.
• a digital ear thermometer, which can be used in children older than 3 months

Plastic tape or infrared thermometers used on the forehead are not reliable.

Some thermometers are more suitable for particular age groups, so follow the manufacturer's directions to get an accurate reading, or ask your doctor or child health nurse for advice.

How can I tell if my child has a serious illness?

Pay attention to how your child looks. They may have a serious illness if they:

• are unusually drowsy or floppy
• have pale, purplish or blueish skin
• have difficulty breathing, are taking fast, shallow breaths or are grunting while breathing
• are dehydrated
• have severe pain that doesn’t go away
• have a seizure
• are vomiting repeatedly, or if the vomit has a green tinge or contains blood

It’s important to know the symptoms of meningococcal disease. This is a medical emergency and early diagnosis and treatment are vital. Think about meningitis if your child is unwell and has:

• a bad headache
• stiffness when moving their neck
• a purple or red rash that does not turn skin-coloured when pressed
• difficulty looking at light
• a bulging fontanelle the soft spot on top of your baby’s head)
• a high-pitched cry

When should I take my child to the doctor?

Your child should see a doctor straight away if they look unwell or have any symptoms of a serious illness. Parents know their children best — if you’re worried, that’s a good enough reason to take them to the doctor.

Your child should also see a doctor if they:

• are less than 3 months old and have a fever
• have had a fever for more than 2 days
• have pain that doesn’t go away with pain-relieving medicine
• have been drinking less than half their normal amount or are not feeding well
• are not passing some urine every 6 hours
• are refusing to use their arm or leg
• have a swollen joint

When should I call an ambulance for my child?

You should call an ambulance if your child:

• becomes unwell very quickly
• is very drowsy or not responding to you
• has difficulty breathing or their lips turn blue
• stops breathing for short periods
• has a seizure
• has symptoms of meningococcal disease
