Waukesha County Reserve Judge Neal Nettesheim said Kiyo Clemons, 35, was holding her baby in court and the child began to grow restless, "interfering slightly with the proceedings" as he started the case, Milwaukee's WTMJ-TV reported Wednesday.
Nettesheim said he and his courtroom workers were surprised when Clemons did not hesitate to lower her baby to her breast and begin nursing.
"The woman simply brought the child down to the area of her breast and started nursing the child. The child quieted down," the judge said.
"The breast-feeding was done very discretely," he said, noting the woman was careful not to bare her breast in the courtroom.
Nettesheim said he considered delaying the case for a few minutes to allow the woman to finish but decided instead to press forward.
"I proceeded to conduct the proceeding and take the woman's guilty plea, and concluded the case," he said.
