- Receive validation errors if:
- Any field is empty when the form is submitted
- The day number is not between 1-31
- The month number is not between 1-12
- The year is in the future
- The date is invalid e.g. 31/04/1991 (there are 30 days in April)

- **Bonus**: See the age numbers animate to their final number when the form is submitted
