Sondra Williams, wife of San Francisco 49ers offensive tackle Trent Williams, shared the heartbreaking loss of her son, Trenton O'Brien Williams Jr., in an emotional Instagram post on Sunday, December 1.

In the reel, set to Beyoncé’s song “Heaven,” Sondra revealed that Trenton was stillborn on Sunday, November 24. The post included footage of her son’s sonogram and delivery, during which he was tenderly cradled by his mother and surrounded by family. Accompanying the reel was a heartfelt multi-paragraph message dedicated to her “forever angel.”

"💔It’s been extremely hard trying to process the saddest Hello and Goodbye that I’ve ever had to endure," she wrote. "Last Sunday night on 11/24/24; I welcomed your lifeless 4lb 8oz 18.5 in long little body at 11:38pm. At only 35 weeks, your impactful and quick arrival didn’t even give mommy time to get an epidural. I’m so grateful to have had your Aunt Katina(who also cut your cord) and nurse Hannah by my side. 🙏🏾."

Sondra and Trent share three daughters—Micah, 15, MaKayla, 11, and Madison, 2. Trenton was set to be born alongside his twin brother, whom Sondra revealed she lost during the first trimester.

Sondra and Trent Williams share three daughters, Micah, 15, MaKayla, 11, and Madison, 2. Trenton was intended to be born with a twin brother, whom Sondra said she lost around the first trimester.

“🙏🏾As much as I tried to prepare myself for our meeting, I wasn’t prepared nor would I ever be,” she wrote. “After losing your twin early in the pregnancy, I prayed and hoped that your diagnosis of Trisomy 13 wasn’t true and wouldn’t be the fate of my long awaited beautiful Son-shine.☀️”

“My firstborn and only son, I’ve always wanted you, but God wanted and needed you more,” Sondra continued. “Knowing you are in Heaven with your Great-Aunt Vivian and that you will Always be our Guardian Angel 👼🏽 brings me great comfort in the midst of all this sorrow. My heart is heavy. Being home without you in my arms has been quite an adjustment. Knowing I will never be able to watch you grow older alongside your sisters has my eyes filled with tears.😭”

Trenton was identified as having trisomy 13, also referred to as Patau syndrome, a severe genetic condition brought on by an extra chromosome 13 instead of the usual two, per Cincinnati Children’s. The syndrome occurs in 1 of 10,000-16,000 births annually.

“🥹I can’t even begin to describe how I felt leaving the hospital without you. Nor how it feels being home celebrating Thanksgiving without my baby in my arms,” Sondra continued. “My heart is broken and my arms are empty.💔 But I know you’ll always be near watching over me and your sisters. 💞👼🏽 And for that, my heart smiles with gratitude. 💙”

Sondra closed the message with spiritual gratitude that she and Trenton were given the chance to “bond for 35 weeks” and that she could deliver and hold her son. “I’m at peace knowing you will never have to suffer,” she wrote. “Although I will never hear your soft coos and cries or see those beautiful little eyes staring up at me, I am grateful to God for the time I shared with you. 💗💙Madison loved listening to your heartbeat and watching your waves of movement in my tummy. Trenton O’Brien Williams Jr., my sweet baby boy, we love you our Forever Angel!💙👼🏽”

Just four weeks before, Sondra shared the heartbreaking news that her Aunt Vivian–who she acknowledged in her letter to Trenton–had passed away.
