Chore Chart / Reward System

Congratulations on number four!
We use a popsicle stick system with our kids (4.5 and 2.5). They each have nine sticks (his are blue, hers are pink) that each have a chore on them. Each day they pick out one chore from the cup and move it to the "done" section of the cup and I pay them 10 cents for each chore. (Sometimes I don't get the chance to pay them right away, so I have a "paid" section too.)
When they have finished all nine chores, they get a surprise, things like candy, extra money, a trip out for ice cream, painting nails time with mom... then we move all of their sticks from "paid" to "to do". They can do as many chores each day as they want (they have done all nine in one day before), but they need to do at least one.
They also have to clean up their toys at least twice a day as part of a responsible member of the family. If not, and after a fair warning, I clean them up and they don't see those toys for a few days. I think what helps this the most is they feel like they have control. Which chore are they going to do? How many chores? And I give them the choice between cleaning up or having mommy clean up, then they deal with the consequences.
My 4 year-old worked extra and saved up to buy her very own bike, which she did in July. There are SO many benefits to a lesson like that.
One bonus I just have to mention is that we never have fits at the store. Ever. Because if they want something I can say "Let's count your money when we get home and if you have enough you can buy it the next time you come."
Good luck! I'm sure you'll find a system that works for you.

We have a chore chart at our house too. I made my own on my computer. I just put in the chores they are responsible for and the days of the week that they are supposed to do them. Once they have completed the chore they color in that box. We have a jar and pom pom system. At the end of each day we look at the chart and they get one pom pom for each completed chore. They count out the pom poms and put them into their jar. At the end of the week they count up the pom poms and trade them in for prizes. The total number of pom poms have different values so they have choice that they can make for the work they have done. The prizes range from candy, to getting toys, to going to lunch at a particular place or trading the pom poms for money. It will work but you have to be on top of it. :) Good Luck

This is a cute one:http://www.amazon.com/Melissa-Doug-Deluxe-Magnetic-Respon...

You can use a point system where they earn points for their tasks and then cash them in for money, a toy, a day out, etc.

Congrats on your new arrival!!

This is the system I use with my boys. It is a real winner because it ties the quality/quantity of work directly to allowance AND teaches the kids to save for important things first. http://www.activeallowance.com/

I hope you enjoy it as much as I do!

We don't do money (yet?) but for my four year old I simply print a spread sheet with her chores and hang it on the fridge every week. It's always the same things, once she's done them we put a sticker in that field. If she does all of her jobs for the day (things like getting dressed, brushing teeth, cleaning up her toys) she can earn a treat, for a perfect week (all chores done during that week) she can earn a little toy or some other reward (going to the movies, watching a fave movie on netflix...).
It's cheap (no need to buy a fancy chart), easy (just use your computer!) you can make up any chore you want and review them (or alternate between kids) periodically.
Good luck!

I've heard the Melissa and Doug one is a real pain. This is the one I bought. Comes with 3 blank ones and you can buy supplemental packs. Of course, you can make your own, but soooooo much easier to just buy this one.
