Babies are naturally warmer than us and sometimes that’s perfectly fine:) Maybe you can get a thermometer to check the temperature objectively, so you can see if it’s a real fever? If it’s real, then you can try tepid sponging to bring the temperature down. And most importantly, keep baby well hydrated with breast/formula milk:)
usually if having fever, only way to check is to take their temperature. Sometimes we tend to put on too many layers of clothes, socks, blanket than it could be just baby body heated up. Remove all these and put only light clothing if temperature is higher than 37.5 than better bring kkh, cause baby having fever is dangerous.
