Early church writers opposed to the baptism of infants?

In his book *On Baptism*, Chapter 18, "Of the Persons to Whom, and the Time When, Baptism is to Be Administered," Tertullian says > According to the circumstances and disposition, and even age, of each individual, the delay of baptism is preferable; principally, however, in the case of little children. Based on the arguments he uses for this, and the way he says it, he is not making a case against paedobaptism the way that credobaptists would now. Nevertheless, he clearly is not in favor of the practice. People obviously interpret different authors different ways. However, I am wondering: are there any other early church writers who are *clearly* opposed to paedobaptism? In other words, I'm not looking for writings that could be interpreted as credobaptist, I'm looking for writings where paedobaptism is clearly spoken against, as in Tertullian.
