ROCKFORD, Mich. (AP) — A Michigan couple with 13 sons has welcomed a 14th into the family.

The Grand Rapids Press reports Jay and Kateri Schwandt's latest addition was born Wednesday evening, five days before the baby's expected due date. WOOD-TV reports the boy weighs 8 pounds, 4 ounces (about 3.7 kilograms) and is 21 inches (53 centimeters) long.

Jay Schwandt was happy that mom and baby had a safe delivery. The baby's name hasn't been announced.

Kateri Schwandt has said she's used to large families, as one of 14 children herself. As with their last few children, the couple decided against learning the baby's sex before the birth. The Schwandts live in Rockford, north of Grand Rapids, and their eldest son is in his 20s.
