none, and all of em
I think of chores as 'assigned tasks on top of regular work' which is to say my kids have none, but the regular work on the other hand they do plenty of..and they are 4 and 2..ok my baby doesn't do any yet.
And no one pays me to do dishes or anything, so I don't pay them...seems fair.
Laundry:
Put own away..soon as you are able to open the drawer and walk in to your room...help fold some (DD does washclothes, DS does hand towels)....more as they grow. Plus they both empty the dryer frequently
Dishes:
Put away all you can reach..soon as you are tall enough to reach, and know what a spoon is..and when NOT to put it in your mouth (bout 2)
toys:
I didn't play with them I am not putting them away! Ok so I do often play with them..and then I do help..help not do! We start about when dropping on purpose is learned..that is the perfect time to cheer when a toy is dropped into a bucket on demand. As they grow I ask them to do more and more.
beds
DS knows how to 'make' his twin bed, DD just got hers this weekend, she makes it after nap..with lots of help. I make it in the AM. For toddler beds so long as the stuffed animals blankets and decoration pillows are on it, I call it made. (same with cribs..but if you are ina crib chances are I am doing the 'making' still) and yes we do make them nearly every day.
floors
the kitchen floor needs done after EVERY meal..DD does breakfast, DD does lunch (I follow up as needed) The split is cause DD takes a nap after lunch...oh and daddy does dinner
.
everything else
Most anything else is as needed, as capable basis...things like putting the towel in the hamper after your bath, or putting the comb back when getting hair done...wiping up the water you spilled or whatever. The above is just the most frequently done list. Prolly more than you asked for.
