Depende na sa age ng baby mo at sa pediatrician niyo, pero usually newborns may check-ups sa 1 week, 2 weeks, then 1 month, and after that every month until 1 year! A few of us schedule it same day every month para madali lang matandaan, like always on the 15th or whatever works sa inyo. Best to confirm with your pedia kung ano exact schedule nila since may clinics na may specific days lang for baby check-ups.
