Aimees been up all night vomiting. Shes not eating and has the runs and a high temp. I know shes caught it off her sister who was sent home from school on Tuesday being sick but shes still not eating now 4 days on. I'm just a bit concerned about Aimee cos shes so tiny and doesn't have any extra weight she can afford loose, shes all skin and bones. How long should I leave her do you think before taking her the doctors? Also what about Nathan, hes only 10 months, does he need to be seen by anyone if he gets it?
