Babysitter - Full-time / Part-time

Hi, I have a 2. 5-year-old and he goes to daycare from 9 a.m. to 12:30 p.m. I will be busy in this coming month and my sister is getting married so I will not be able to watch him all day for this month especially, especially during the events themselves. I have also recently become a single parent so I am in need of help so I may keep a nanny from now on and want to make sure he has the best chance at growing up and developing feeling loved and encouraged.
