The new CDC Developmental Surveillance Milestone Checklists have been revised so that:
- Duplicate milestones were removed
- Vague language that was unclear to families was removed
- Checklists now coincide with every well-baby/child check-up from 2 months to 5 years of age
- Additional social and emotional milestones were included
- Open-ended questions (e.g., Is there anything that your child does or does not do that concerns you?) were included to facilitate discussions between families and health professionals
