So my 5 year old daughter came home from school tired Friday. By the night she has a temp and has a headache and had a bad dream. I gave her calpol to help her headache. Anyway she still has this high temp and headache and tummy a she, blocked nose and slight cough. I took her to the doctors who says it's just a viral infection but it's Monday now and no improvement! Is this a normal thing to happen?
