10month baby has fever range from 100 to 102.5.also Saw doctor prescribed ibuprofen & Tylenol (acetaminophen).can I use ice pack to reduce hot in his head, bathe him?

Yes but. fever isn't a bad thing. It is part of the body's way of fighting infection. It is good to treat the fever, because having a fever feels awful, but the fever won't "cook his brain" or anything bad like that. Alternate tylenol (acetaminophen) and ibuprofen as your doctor suggests, and if his symptoms worsen or don't improve, see your doctor again. Hope this helps!
