How can I bring in some extra money by working at home?

I have 4 month old twin boys and I would love to stay home with them, but I need to bring in some money to help my husband. What can I d moso? I know there are alot of things, but most are scams, plus I am hesitant about putting money down. I need something legit! I’m not against starting my own business, but doing what? Please respond only if you have good info…no scams! Thanks
