My 69 year old Aunt is mobile and independent

My 69 year old Aunt is mobile and independent. but after an accident 2 months ago, she is currently recovering from brain trauma. Therefore, she does have a mental disability right now because at times, she can be very confused (due to the diffuse blood in her brain which is slowly resolving). until she recovers, we will need someone to help in case of her needs. When she doesn't need help, the other duties may include occasional baby care..etc. this is a short term position (at least 3 months-5 months) depending on when the senior recovers. Once she recovers, we may look for someone specifically for our 3 children at that time. Therefore, the potential candidate may extend her contract after 3-5 months.
