For those of us who are committed to the practice of paedocommunion, Doug Wilson writes that we should explain the Supper to our children:
Young children should have the Supper explained to them by their parents in each observance of the Supper, and they should be able to attend to what is said. Please note that we are not requiring that little children be able to explain the Supper before they may partake. They are recipients; they have the Supper explained to them. We feed them the bread and wine in much the same way we begin speaking English to our children when they first arrive in our homes — not because they understand it, but rather so that they might come to understand it. It is similar here. We are not asking for anything to arise in the child or manifest itself before he is qualified to receive. He is receiving and learning, not giving and teaching.
