My son was not feeling well last night, complaining of feeling really hot and dizzy. I took his temperature by ear and it was 34.4 in both. I never realized til last night that this isnt the first time his body temp has been low. Ive also seen it as low as 35 when hes been not feeling well. I would think he'd have a fever and his temp is low. Should I be really worried or could it be a normal thing?
