Chores for younger kiddos?

Alix

My stepson will be 4 at the end of this month. usually every couple of months I go through his toys and get rid of some. I try to keep ones that I know he is still attached to from when he was younger and still plays with. Now that he will be 4, his dad and I kind of want to implement more chores around for him to do. Like, going through his toys and picking out ones he wants to keep. But with that, the dilemma is, he is 4. He wants to keep everything. He is a kid.

So when did you guys start letting your kiddos help out with chores or going through their toys?

Update:

We have my stepson every other weekend and then a weird summer agreement, but we have him mostly during the summer. He does do chores like he loves to vacuum, sweep up, help take garbage out, and help with dishes and cleaning up his toys. What makes it hard is that as far as we know, his mom doesn't implement the same rules or ideas that we have as there is little communication between houses to make them similar in that way. His mom believes that she will parent her way and my fiancé will parent his way. She has told us this straight out but we believe there should be some compromises on rules and stipulations for their son at both houses to avoid confusion for their son, yet she does not agree on that. So when is comes to chores, he doesn't want to do them or will tell you he doesn't have to and "I hate you" "you're not my friend" when you ask him to do something. We are hoping we can work with him on that stuff throughout the summer, but it will be difficult to get his mother to see it that way.
