Hi everyone. I am the employer and just received a letter asking for the following
Explanation why a caregiver is mandatory at this time and at your children’s age(s). This explanation should address the following points: If you have not hired a caregiver in the past: 
Provide a clear description of the exceptional circumstances behind the need for a FULL-TIME caregiver (which equals at least 30 hours of paid work each week) when you did not require one in the past.
How frequently will you require a FULL-TIME caregiver and what other options, other than hiring a caregiver, were explored prior to making this application?
Can someone kindly guide me the best reasons to put here? Applicant is my niece by the way.
Thank you in advance.
