Dd2 (5) has been poorly sinse early this morning, probably just a virus (as i have been poorly too), her temp is very high (almost 40) but she often has a high temp when poorly, she's led on the sofa and keeps falling asleep. When i lie next to her i can see her heart beeting very fast and the veins in her neck pulsating fast. Is this normal? is it just her body coping with the fever? or should i be worried?
