educatingchildren77: It’s hard not to worry when your baby is crying and her temperature is soaring, but a fever rarely causes any harm. A fever is part of your baby’s natural defence against an infection.
However, a fever can be more serious if your baby is under six months old. It is fairly unusual for young babies to develop a high temperature, so this can be a warning sign that something is wrong.
See your doctor straight away if your baby is:
under three months old and has a temperature of 38 degrees C or more
under six months and has a temperature of 39 degrees C or more
If your baby is older than six months, the height of her temperature or how long it lasts may not always determine how poorly she is. Your instinct that your baby is unwell is just as reliable as measuring her temperature. However, it can be useful to use a thermometer so you know what is normal for your baby.(babycentre)
