Behavior Charts

[beaute_marquee]

For those who use them:
Do they work?
What behaviors do you put on them?
Do you have a reward when they get so many stickers?
How young did you start?

I have a 2.5yo that might grow up to be an axe murderer if we don't get a handle on him. Joking. He's a really good kid, but we haven't been expecting much of him chore wise and stuff, and I think it's time he starts picking up toys, and helping make his bed and little things around the house. Also, he's just started throwing MASSIVE tantrums (that's where the axe murderer comment comes in. It scares me how violent he gets), and I think it might help to have a reward for keeping his temper in check.
Any advice?
