We are a family of 5, just me(mom) and my 4 boys. They're very independent and decent kids.
Just keep an eye on them while I'm at work, make sure they are safe and fed. I will leave everything set every day for the, so in your case is minimal what you might have to do.
I don't have the exact days that I will be working all I know is that I have to work 1 day of the weekend mandatory for now. Not sure yet if its 3 or 4 days a week.
