Luther on Children at the Table

Martin Luther said many fine and provocative things with which we should disagree. But with the following word about children at the Table of the Lord paedobaptists ought not to disagree:

When in 1 Corinthains Paul said that a man should examine himself, he spoke only of adults because he was speaking about those who were quarreling among themselves. However, he doesn't here forbid that the sacrament of the altar be given even to children (Vol. 54, Luther's Works, p. 58).

Luther seems consistent biblically and theologically with his paedobaptist stance. So why do so many paedobaptists today act like credobaptists when it comes to the Supper?
