NFL star and wife mourn 'forever angel' son born at 35 weeks after losing his twin earlier in the pregnancy

San Francisco 49ers' Trent Williams and wife Sondra have shared the devastating news their son was stillborn on December 1. 

The wife of the NFL pro offensive tackle posted a reel documenting her pregnancy and opened up about their loss in an emotional caption. 

She honoured her son, Trenton O'Brien Williams Jr, who was born at 35 weeks, and called him her "forever angel". 

"It's been extremely hard trying to process the saddest Hello and Goodbye that I've ever had to endure. Last Sunday night on 11/24/24; I welcomed your lifeless 4lb 8oz 18.5 in long little body at 11:38pm," she wrote. 

"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."

She shared that they had lost Trenton's twin earlier in the pregnancy, and learned Trenton was diagnosed with trisomy 13, a rare genetic condition where a person has three copies of chromosome 13 instead of two.

Survival beyond the neonatal period is uncommon for babies with the diagnosis, according to Better Health. 

"As much as I tried to prepare myself for our meeting, I wasn't prepared nor would I ever be. 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," she continued.

"My firstborn and only son, I've always wanted you, but God wanted and needed you more."

Sondra added that Trenton is with family in heaven now and will always be their guardian angel, something bringing her some comfort during this time. 

The couple, who share daughters shares daughters Micah, 15, MaKayla, 11, and Madison, two, are struggling with being home without their son. 

"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. 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," she wrote.

Sondra said she's grateful for the time they spent together, but she's struggling with a broken heart. 

"Thank God for allowing us to bond for 35 weeks and for me to birth you so I could hold you in my arms. I'm at peace knowing you will never have to suffer. 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," she wrote. 

"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!" 

The couple has been flooded with supportive messages and condolences from followers and football fans since sharing the sad news.
