“It can be difficult to tell when a baby or toddler is seriously ill, but the main thing is to trust your instincts. You know better than anyone else what your child is usually like, so you’ll know when something is seriously wrong.”
“Is your baby or toddler seriously ill?”. The NHS website. Retrieved 29th January 2024
As well as trusting your instincts it is also worth knowing about the symptoms and signs of serious illness and when should take action, which is covered on this page.
The traffic light system (with red, orange and green coloured tables) is used for identifying risk of serious illness in common presentations such as with fever (high temperature), rashes, difficulty breathing, accidents and more. The red table for each presentation includes features which would suggest urgent help is needed at a hospital emergency (A&E) department.

It is likely you have been sign posted to information on spotting a sick child, as part of a process called “safety netting.” This is explained in detail under
In summary:
“Safety-netting advice is information shared with a patient or their carer designed to help them identify the need to seek further medical help if their condition fails to improve, changes, or if they have concerns about their health.”

As the NHS points out in most cases of high temperature
“you can usually look after your child or baby at home. The temperature should go down over 3 or 4 days.”
There are occasional situations when a high temperature is combined with other symptoms and signs and you should then attend A&E. The list below includes symptoms and signs of sepsis (including meningitis septicaemia)
Call 999 if your child:

There are some features of shortness of breath in babies and young children which are worth knowing about and may indicate a need to call 999 or go to A&E.
These features will be associated with fast breathing/struggling to breathe but are in addition and include
Though not common, each of these features can occur in many infections involving the chest and/or airways and are best understood by considering 3 childhood conditions with the feature highlighted. Note at the bottom of each condition there is more information on each feature (including in some cases a video of the feature).
The 3 conditions included are:
Bronchiolitis (demonstrating the importance of intercostal recession)
As the NHS suggest
“Most cases are mild and clear up within 2 to 3 weeks without the need for treatment, although some children have severe symptoms and need hospital treatment.”
“While it’s unusual for children to need hospital treatment for bronchiolitis, the symptoms can get worse very quickly.”
“Call 999 and ask for an ambulance if:
The term given to “muscles under the ribs sucking in with each breath” is called intercostal recession and this can be clearly seen in the attached link which includes a number of the other common signs of serious respiratory distress Signs of Respiratory Distress in Children – Physiopedia
Croup (demonstrating the importance of stridor and abdominal movement)
As the NHS suggests
“Croup is a common childhood condition that mainly affects babies’ and young children’s airways. It’s usually mild. “
However, on rare occasions when you might need to attend A&E it is worth understanding what to look for
Call 999 if:
Stridor (“breathing sounds different”) and Intercostal recession and abdominal movement (“their tummy sucking inwards”) can clearly be seen in the attached link which includes a number of the other common signs of serious respiratory distress Signs of Respiratory Distress in Children – Physiopedia
Pneumonia (demonstrating the importance of cyanosis (blue skin or lips))
As the NHS suggests
“Call 999 for an ambulance if someone you care for:
Blue skin or lips (cyanosis) can mean there’s reduced oxygen in your child’s blood and as such indicates you should call 999 and attend A&E.

As the NHS suggests
“Dehydration means your body loses more fluids than you take in. If it’s not treated, it can get worse and become a serious problem.”
In the general population babies, and young children are more at risk of dehydration.
“Take your baby or child to the GP urgently or go to A&E if they:

Minor head injuries are common in children, and most are not serious but there are certain features which should be assessed in A&E, and these are included in the article from the NHS (if you are not sure you can always contact 111)
From the NHS, Patient info and NICE
Head injury and concussion
A practice clinician may tell you that your child has a specific condition such as bronchiolitis. The NHS website has well organised articles where they include information on specific conditions, including when you should call 999 (or go to A&E) or call NHS 111(or ask for an urgent GP appointment).
Examples include
If you are not sure whether you should call 999 (or go to A&E) or instead ask for an urgent GP appointment then 111 can advise you

NHS 111 can help if you think you need medical help right now
