its not like every child given aspirin
in any febrile illness develops Reye's syndrome. so, keep calm and there is nothing to worry if your child is fine and doing well.
the only thing you have to be vigilant about him getting any pain abdomen, vomitting, rashes, lethargy
you should be careful in future of not giving your child any drug containing aspirin or salysilate in it, as it is not recommended even for teenagers unless specifically indicated.
about giving paracetamol
, you can wait for 6-8 hours after giving ant analgesic
before giving another one and that too only when required.
wish for early recovery of your son.
