Hi- we have a 4 year old and what works for us is a chore chart. She has 6 chores that she is expected to do each day: make her bed, get dressed/brush hair/brush teeth (with mom's help), clean up her toys, wash her hands before all meals, clear her dishes from the table, and no bedtime battles. If she does all of those things, she can do 4 extra chores for one quarter each: put away her laundry (she has her own little basket in the laundry room),put away her clean dishes from the dishwasher (all plastic) and all silverware (except knives), put away her little brother's toys (he's 16 months), and no time-outs for the day. Again, she just turned 4 in December, but she has had at least 6-8 clean sweeps- 2 of which were last week. She's more motivated on some days than others, but hey- we all are! If she gets a clean sweep- all 10 chores, she gets an extra quarter for the day. If she doesn't do all of the first 6 chores, she doesn't get quarters for extra chores. But, we don't make a big deal out of that- it's just too bad, etc. I tell her that just as mommy has chores like cooking and cleaning, daddy has to do chores at his work, she and even her little brother are expected to help with chores.
Every Saturday is payday and she separates her quarters to see if she has any new state quarters (she collects them). Out of the pile that's left, she puts 1 quarter in her baby Jesus bank, 1 quarter in spending, and 2 quarters in savings. When she gets money, she tends to put the full amount in her baby Jesus bank (she has a really tender heart). She just took $15 (yes, $15 of her CHORE money- not gift money) to church on Sunday for her offering. She likes to take paper money, and at this point, we do it when she wants to. She knows the money is in the Jesus bank, and that's the point, although we should be more dilligent about taking every Sunday. There's always something to do better in parenting, isn't there!
Anyway, that's what we do and what works (for the most part) for us. If we forget to do the chore chart a night, we try to catch up as soon as possible.
I will say that our daughter is very engaged and interested, otherwise, I'm not sure this plan would work. She LOVES positive attention and that's probably why this works well for us.
