While the mother was only convicted in Heather's death, she ultimately admitted to killing both, according to the News-Democrat. A jury convicted Sims in 1990 for the first-degree murder of Heather, and she received a life sentence.

Stone has long argued postpartum psychosis was to blame for the deaths Sims' daughters - 13-day old Loralei Sims in 1986 and 6-week-old Heather Sims in 1989. “It is a recognition that postpartum psychosis is real and the women who suffer from that mental illness need to be treated and understood and not brushed aside with having the ‘baby blues.’” “This was a great victory for women, a great relief for me and a great gift to Paula,” her attorney, Jed Stone, told the Belleville News-Democrat. The Illinois Prisoner Review Board board granted Paula Sims, 62, parole on Thursday in a 12 to 1 vote, the Associated Press reports. An Illinois woman convicted of killing her infant daughter, and who reportedly admitted killing another child years earlier, is free after being granted parole.
