Chores should be according to age/ability of their age and coordination and awareness of cleaning supplies and how to use them.
ie: can the 5 year old, actually empty the dishwasher and put it away? Emptying the dishwasher, means putting away all that stuff. I imagine lots of broken things being dropped, not to mention, lots of the dishes/cups may be on a high cupboard that a kid cannot reach without having to use a ladder. Safety issue.
Then, can the child actually pick up the ENTIRE room and put away just like you? No. Young kids do not have our cleaning ability.
So you let them do it to their best, of their, ability. Or comprehension and age.
Then, there are things that Mom/Dad does. And things the kids help with, as being a part of the family, and doing supplemental cleaning and picking up.
As far as dusting, well that seems easy enough. My 6 year old can do that and does. But, he also misses a lot of spots. Fine. But he does it the best he can or has the energy to.
I don't make my kids clean the bathroom though. I prefer to do it. My kids are 6 and 10.
Then, there is the time it takes for a kid to clean all of these things. Versus an adult. For an adult, it can take all morning to do it all. For a child, how long will it take them to do it all? And how "good" do you expect them to do it?
Then, if they are doing these chores, then the hope is that they are taught "how" to do it all. First. Giving them tips on it etc.
A 5 year old and a 7.5 year old, has vastly different abilities, to do the same type of chore.
Then, will the kids do it by themselves or be spot checked or supervised while doing it? They may think they are doing it well. But then when you come home, and find it not to your liking... will it be a problem or not? And for a 5 year old, even just spraying vinegar spray on surfaces to clean... they may over-spray. My son once, was cleaning the mirrors. He was so proud. But, he sprayed too much. And it got on the floors. He did not realize that. Even if I had given him tips on it, just before. I did not scold him or deduct anything. Because, he DID do what his chore was. And he did it to the best that he could.
And, to a kid, what does "picking up the playroom" mean? Kids need clarification.
Any "rewards" that they are given for chores, should be per their age and ability. Otherwise, it will not be fair.
My kids do, what they are able to do per their age.
Then, what does the Mom and Dad do? Per chores?
Does the Husband, do any????
Often, the kids are expected to do most chores. While the Husband is not even doing any. Contradictory.
