Throughout her pregnancy, Snider underwent intensive treatment that included chemotherapy.

"They couldn't give her too much chemo because it would affect the development of the babies," Snider's brother, Chris Snider, told KGO-TV.

Snider gave birth to twins Nico and Camilla on March 16 via cesarean section. Right after, she underwent surgery for a hysterectomy.

She died of heart failure a day after her surgery, on March 17.

“She made sure those babies would live,” her brother said. “She traded her life."

“What gives me peace in my heart is she got to see those babies and hold them, and be with them a little bit,” Snider's friend, Larina Campanile, told KGO-TV.

In addition to Camilla and Nico, Snider is survived by two older children, Aubrey and Maddie.

KGO-TV reported that three GoFundMe pages have been created to help Snider’s children and help with memorial costs.

Campanile set up a GoFundMe page for her friend to help the family with "any costs necessary in helping through this difficult time," according to the page. It has surpassed its $6,000 goal.

Another GoFundMe page was created by Vanillape Crude. According to that page, the funds raised will help Jamie Snider's partner and the twins' father, Heath Coigny, with costs to care for the children. Coigny's sister, Willow Coigny, and her husband, Kevin Smith, will be taking the family into their Pelham, New Hampshire, home. More than $36,000 of the page's $80,000 goal has been raised.

A third GoFundMe page was created to help with memorial costs. It has surpassed its $4,000 goal.

Snider’s memorial service will be held March 30 in Palo Alto, California.
