Normal body temperature for healthy babies is in the range of 96.8Â°F to 98.6Â°F, or 36Â°C to 37Â°C. If the baby's body temperature rises above 100.4Â°F to 101.3Â°F, then it is considered as indication of fever. If it falls below 96.8Â°F then the child has low temperature and needs immediate warming up.
