I know many families who wait until the child is big enough to be a "real help" but I think that's too late. Some wait until the child is 4, 5, 6, even later! By then, you will need to undo learned habits, routines, and ways of life. Then the child feels the abrupt change in policy is unfair and that you are making unfair demands on them. Instead, why not just do it from the beginning? Sure it's way easier for me to just do the work than take the time to train my toddler to help me, and do it with me. But that would be counterproductive.
Don't get me wrong, I love serving my children, doing things for them, etc. And I do. But I also don't want them growing up with the mindset that Mom is the servant. Then eventually, when she pushes back on that, a whole new battle of whining and complaining ensues. As one person put it, "if you serve them until you are confident they are fully capable of serving themselves, you have cultivated slothfulness in them." Sometimes parents don't plan, they react. They get flustered with doing all the work, serving and serving, and feeling like no one is grateful, and then they react. They decide that the "kids needs chores" and "the kids should be helping out around here." And all of a sudden the apple cart is turned over, and confrontation ensues. No planning happened. "They are trying to fix something that is broken, rather than mold something that is growing." We are huge on training. Training him how to do things from the beginning. It's easier and smoother that way.
Obviously we don't make inappropriate demands on Mekonen. That would be exasperating and discouraging. But instead, we teach him as he is able, from the beginning and expect a happy heart in the meantime.
