The application currently allows registering a child (Son/Daughter) with an age greater than or equal to the parent’s age, which is logically incorrect.

For example:

• Parent age: 45 years
• Child age entered: 46+ years
• System allows submission without any validation

Steps to Reproduce:

1. Register a Household / Parent (Father/Mother) with age (e.g., 45 years)
2. Add a Family Member as Son/Daughter
3. Enter age greater than parent (e.g., 50 years)
4. Submit the form

Expected Result:

• System should validate age relationship:
  • Child’s age must always be less than parent’s age
• Proper validation message should be shown (e.g., “Child age cannot be greater than or equal to parent age”)
• Submission should be restricted

Actual Result:

• System allows invalid age entry
• No validation or error message is displayed
