5 1/2 months old and first fever

Ethan felt warm so I took his temp......its 100.3
I called the DR oncall and he said not to worry- that if it reaches 101 then to call back.
This is my first child so I dont know whats normal.
100.3 seems high for a baby to me?
He said to make sure that he stays hydrated and give him 4-6 oz of water.
He isnt cranky or fussy.

Should I be worried with 100.3?
Luckily we do have a DR appt tomorrow for his monthly check.

Thanks!

I wouldn't worry, I am pretty sure babies temperatures run a little higher.

Ped told me its not a fever until its over 100.4.

100.3 technically isnt considered a fever, 100.4 is. A temp like that is probably due to teething. I would give him a little tylenol before bed.
