2.  Teething

One of the common reasons why babies’ temperatures spike while sleeping is because they might be teething. The growing new set of teeth that comes with might come with some discomfort for your baby.

Parents should, however, take cognisance of the fact that teething does not cause a high-level fever. A high-level fever is measured 100.4 F and above, which indicates some other happenings in the baby’s body, like an infection of an illness in which you need to take the baby to the clinic.

It is also important to note that if your baby is teething. He or she would have shown some noticeable signs during the day like chewing on toys, biting fingers, constantly biting the nipples, drooling, gum inflammation, and gum rubbing, to mention a few.

When your baby might have been sleeping in the same position and becoming uncomfortable with it because they are stressing a particular part of the body, your baby might not be able to change style and is invariably stuck.

Parents should avoid over-dressing or bundling them to sleep for babies, especially those below 3 months and young toddlers. A baby can run at a high temperature because of this.

The takeaway is to ensure that you do not swaddle a baby to sleep, as this is one of the most typical causes of fever at night.

5. Reaction to immunisation/vaccine

When a baby takes a shot of immunisation, because the body received a foreign content and is a straightforward system, the baby tends to react to it. But, on the other hand, the baby might still be hurting from the pain of the injection insertion.
Usually, after taking the immunisation, the baby tends to sleep off after crying, and when it is night again, the baby’s temperature might spike again. This is normal and common. Parents are usually dissuaded from giving the baby any medication because it is just meant to last for 24 hours, and it will be gone.
