The thing is, when you work you work and your child isn't watched so she ends up missing out. So you have to decide if you want to go to work to help out then stay at home when money is better or cut more spending and help that way.
If you take in ironing your utilities will go up, if you do laundry for someone then same thing.
If you want to do a job and make a living I suggest you investigate the licensing laws for your state and run a home child care where you can actually make a living that is real money.
This is truly the only way I know for someone to stay home and make actual money.
You get to write off so much of your daily living expenses on the taxes and you can do the paperwork and get most of your food bill reimbursed through government programs for child care businesses.
I think most of the mom's I know who really work at home end up up putting the kids in child care full time so they can get their work done without interruptions.
