How can I make income from home WHILE being a stay at home mama? Any ideas?

My poor husband works his ass off everyday (even weekends at times) long hours and everything for our family. I know he stresses because he runs his own business that is freshly new so sometimes he’s busy, other times he’s not.

Money is tight. I want to be able to help out a little. Even if I can help with groceries, or bills, or anything really...

Any ideas?! Please help!!!
