I don't know what job experience you have or what your resume is... but try going to www.monster.com and search for "telecommuting jobs." using the search words "telecommute."
As you may know, "monster.com" is a major online jobs search site. Corporations use it too, to recruit employees.
With telecommuting, the whole idea is you work from home... on your computer.
Also, you can search online for "freelancing" jobs. Depending on of course, your job experience or specialty, or resume.
You are young, but you seem very responsible and a dedicated worker... bravo for you!
Another option is, babysitting. Which is an at-home "job." ANd the need for babysitters is always there. BUT, you will be having another baby soon, so it may not be great timing for this kind of "job."
I would search job/employment websites, like "monster.com" and see what telecommuting jobs there are.... therefore, you are a real paid "employee" and not spending money to someone else in order to "sell" something like products.
ALSO, try asking your present Employer... if they have any telecommuting type jobs... since you already worked there and have a work history there.
Or, you can sell things on E-bay. But as with any sales, your income will vary each month.
Good luck...
Oh, as a side-note... there is something called Free Cycle- www.freecycle.org where you can get things you need for free. Especially important and useful for anyone with a budget and children.
For me, I have an online boutique, thru Cafe Press, where I design t-shirts among other things. I am not a graphics artist "expert" nor a "professional"... but it is something I enjoy and I taught myself how to use my own graphics software. Long story short, I have fun with it and can make some nice pocket change for myself. www.cafepress.com/littlegoogoo
I was all self-taught... and did TONS of research on it. But it is so fun!
All the best, I am a SAHM too, and I understand your feelings on this. But as with anything, it is going to take a LOT of research... for you to find something, that will fit you, that you can do from home. I spent HOURS and MONTHS researching things too....and only you will know for sure, what will appeal to you or what your previous work history can apply to, or what skills you have so that you can branch out into another "career." I even did babysitting too. This is a guarantee income as well. But when I had my 2nd child, I stopped babysitting.
All the best,
