Thinking about starting a blog

St

I'm a SAHM and I was thinking about starting a blog to bring in some money. Does anyone here blog and if so could you give me some pointers on how to be successful? I know this isn't going to pay the bills but I just want to feel like I'm contributing financially and most at home jobs are call services and with a loud 7 month old I don't think I would be able to do that. Any other work from home opportunities that are not pyramid schemes?
