Mother's Helper Monday & Tuesday Evenings

I need someone to come and stay with my 9-year-old daughter and my mother Mondays and Tuesdays from3 p.m. to 9 p.m. while I'm at work. My mom has been watching her (the three of us live together) but she has recently been diagnosed with a serious illness and needs more rest than usual and is not entirely up to watching her solo at the moment. It is my intention to have dinner prepared for everyone (including the sitter) before I leave for work. I will need to know about diet restrictions and food allergies, naturally.
