Nanny Needed For My Children - Now Hiring

I am starting a new job 8/31 and My son (12) is starting soccer through his school 8/27. I dont have a schedule yet but he may need drop off/pick up for practice before school is back in session. I will need full-day care on scheduled superintendent conference days and school breaks. He can prepare his own snacks etc but I am not comfortable leaving him alone for a whole day as he can become irresponsible when left unattended. He is a wonderful smart kid he just needs supervision honestly. We have a cat (a total love bug) and my complex are non-smoking premises.
