Sinead O'Connor was the mother of four children, but it appears that she had a special bond with her son Shane Lunny. O'Connor shared her son, who was born in 2004, with Irish musician Donal Lunny. O'Connor discussed her relationship with Shane in her 2021 book "Rememberings." In it, she wrote (via People), "He is the child who is most like me, I believe, to look at and by his nature — although he is of course the version of me with logic and reason."
After her son was confirmed to be dead in January 2022, O'Connor, per CNN, tweeted on her old account, "May he rest in peace and may no one follow his example. My baby. I love you so much. Please be at peace." In the days that followed Shane's death, the publication reported that O'Connor tweeted several tweets that suggested she was going to hurt herself. Ultimately, O'Connor apologized for the tweets and was hospitalized. In June 2022, O'Connor canceled her performances for the rest of the year to try and process her grief.
In a video posted on Twitter weeks before her death, O'Connor addressed her followers and said, "I look like s*** either way, which is why I didn't want to make a video. Before adding, "But you know the way your kid unfortunately passing away — it isn't good for one's body or soul, to be fair."
