Military mommas - needing tricare help!

Amy
FTM here due in a month. Any enlightenment on how I'm supposed to make my first pediatrician appt in the hospital is appreciated. Am I supposed to make the first appt on post or can I skip that and go straight to a pediatrician without a referral? I did the whole tricare brief thing way back, but how am I supposed to remember any of that when I need it?!
