WATERLOO, Iowa (AP) — A Waterloo hospital is seeing a baby boom. The Waterloo-Cedar Falls Courier reports UnityPoint Health-Allen Hospital reported delivering 142 babies in May, smashing the hospital’s old record of 121 babies set in September 2017. The record is especially surprising because the spring isn’t usually a busy times for babies at the hospital. Last year, 86 births were recorded in May. The births came as the hospital already was dealing with coronavirus cases and precautions that put extra stress on staff.
