A fever is not fun for anyone…and when it comes to a baby, a fever can really make Mum and Dad sweat. While a fever can be serious, it is also a normal part of growing up. Fortunately, a few simple fever facts can help you figure out whether you should be concerned about your baby’s temperature…or if you can chill out.
As parents gain experience, they can often just feel the baby to tell if they are warm. Of course, babies also feel hot and sweaty when they have been in a warm room or are overdressed. But most babies who feel warm—but do not have a fever— have a normal digital temperature.
A digital thermometer is a 'must have' in your baby’s first aid kit. Digital thermometers usually have a plastic, flexible probe with a temperature sensor at the tip and an easy-to-read digital display on the other end.
A normal temperature for a baby is about 36 to 37.9 degrees Celsius (usually it is around 37 degrees, but there is some variation from person to person). You will know your baby has a fever when their rectal temperature spikes to 38 degrees Celsius or higher.
Any baby under 3 months with a rectal temperature of 38 or higher, always, always, always needs to be checked by a healthcare professional. And any child with a fever over 40 degrees needs to be evaluated—so if you see that number, do not wait to give your provider a call!
Most often, fever is caused by infection. When your baby or toddler has an infection, their body temperature rises as their immune system suits up to battle the illness (hey, fighting off bacteria and viruses can really work up a sweat!).
Vaccines can also cause a brief fever, which is a normal reaction that signals that your baby’s immune system is working to make important antibodies to prevent disease.
Your child's body temperature can rise over 40 degrees Celsius by overheating, such as being in a hot car. This is an emergency situation where your baby needs to be cooled as soon as possible and seen by a doctor.
Though it is possible your baby might have a fever and be constipated at the same time, constipation itself does not cause fever. If your little one is constipated and has a fever, be sure to call your doctor—it is possible there is an underlying health issue that is behind both.
The idea that teething causes a fever in babies is largely a myth. Research has shown that teething does not make babies sick. If your teething baby has a fever call your doctor to rule out an infection.
A fever can cause young children to become fussy, lethargic and sweat so much that they become dehydrated (dark yellow pee and a dry, sticky tongue). That is why it is good to offer plenty of fluids and medicine to bring down a fever.
One of the signs that make paediatricians the happiest is when a baby wants to play a little…even if they have a fever. Their body temperature dropping even one degree can help them feel better.
You do not have to do anything to treat a fever if your baby is drinking and wetting nappies adequately. If they seem content and are not in any discomfort, medication is not necessary. However, there are a few things you can do to make them more comfortable:
A fever on its own is not necessarily concerning, but combined with certain other symptoms, you will want to call your healthcare provider for advice or head to an A&E. These can include:
A fever can be frazzling, so so not hesitate to call your healthcare provider with your questions. It is always better to be on the safe side when it comes to your baby's health.

Es importante que, en preparación para la lactancia y durante la misma, las madres lleven una dieta saludable y equilibrada. La combinación de lactancia materna y alimentación con biberón en las primeras semanas de vida puede reducir la producción de leche materna y es difícil revertir la decisión de no amamantar. Si decide utilizar fórmula infantil, debe seguir las instrucciones cuidadosamente.
