By what you state it appears that the child is having fever
of 102 for only the past day or two. I would suggest that you get her examined by a doctor who will prescribe medicines for the cough
, blocked nose and fever. In the meantime do sponging of the whole body to bring down the temperature and keep the baby in a cool environmento of a cooler or air conditioner. The vomitings can be a part of the illness.
Wishing your baby a speedy recovery.
