How to earn while you're at home?

I've resigned from my job more than  2 years ago as a call center agent. It was a decision, my partner and I made, because our firstborn was growing fast. We couldn't find a nanny for him too. And, it was also hard for us to leave him under someone's care, whom we didn't knew at all. 

My son is turning 4 years old now and I just gave birth to another baby boy 6 months ago. My husband works his ass off for 8-9 hours per day for 5 times a week just to give us our needs and for the bills.  People wonder how do we manage our expenses if only one of us has a decent job? Well, I earn too. I earn too, believe it or not. 

I'm a stay at home mom but I have lots of ways to earn money. I'm going to share it to you in this post.
