The next scheduled appointment should be at 6 months for this infant. Standard doctor's schedules for infants are for them to be seen at regular intervals of less than a year while they are under 2 years old. A normal schedule would be to have them seen at 2 months, 4 months, 6 months, 9 months, 1 year, 15 months, 1.5 years, and 2 years. The time incrementally increases over the life of the child until at a point, the child should just be seen once per year.
