usually the first Dr appointment is 3 days after for a weight check. Then you need to schedule one for two weeks after birth so they can run a PKU. (they give this card info to you in the hospital) Then you don't have to go back for anymore appointments till your baby's 2 month shots.
Newborns typically see a pediatrician at 1 week old, two weeks old, two months, 4 months, 6 months, 9 months, 12 months, 18 months, and 24 months. You can do the math to find out how much all of those visits would cost.
