Mothers need help, and thankfully, children need to be a part of their team! I happen to be terrible at delegating, and I suspect that many moms struggle with it, too. But assigning chores to my children has been an enormous help on a daily basis.
If one of them is moving the clothes from the washer to the dryer, I can be grading homework. If one of them is unloading the dishwasher, I can be preparing dinner. No chore is too small to be a blessing! It fills an immediate need, and it prepares my child to be a productive adult one day.
