This seems like symptoms of the gums preparing for teething. However, this process can take anywhere from two weeks to two months. Usually, when a tooth is about to erupt, fever can be added to these symptoms. Of course, it varies for everyone, but when our baby was teething, he had a high fever up to 38°C. I gave him syrup and wiped his body with cooling wipes, T-Control. Special cooling wipes for regulating body temperature. Within half an hour, the fever would subside, and the baby would already be playing.
