Blogger Laura Merritt Walker Shares Son, 3, Died After Tragic Accident

While they navigate the impossible, the couple are receiving support from family, friends and fans.

“All the moms on the internet are surrounding you with a massive hug,” one user wrote. “There is nothing we can say to stop the pain. We are just so sorry.” Meanwhile, Bachelor Nation’s Raven Gates commented, “I am beyond sorry, there are absolutely no words. I’m praying the Lord gives you peace and comfort beyond all understanding.”

The Walker family celebrated Callahan’s third birthday in October with an Oktoberfest-inspired birthday party, which they dubbed “CALtoberfest.”

“Happy 3rd Birthday to our precious boy,” they captioned the post, which featured images of the family dressed on theme. “We had the absolute best time with this party theme!! So grateful for these wonderful memories and getting to celebrate Callahan turning 3!”
