Morgan Beck and her Olympic Alpine skier husband Bode Miller lost their 19-month-daughter Emeline earlier this year. She drowned in their pool.
Beck took to Instagram over the weekend to share a heartrending picture of Emeline's final moments, and it showed the toddler in her mother's arms and hooked up to machines.

Beck explained in the caption that she wished for just one more day to hold her baby. She added that Emeline's "footprint would forever be left on this world."
The distraught mother hoped that Emeline would "continue to work through" them to help raise awareness and prevent even more deaths. She wrote:
"I told you as I held you in this moment that you could still change the world, you could still move mountains."
Back in June, Emeline lost consciousness when she fell into their pool at their Californian home. Emergency responders performed CPR and rushed her to hospital.
She lost the battle later that day, and her parents said on social media that they were beyond devastated and never fathomed that they would "experience a pain like this."
Beck and Miller also share a three-year-old son named Nash Skan, while Miller has two children from a previous relationship - Samuel, 5 and Neesyn, 10.
Beck is expecting their third child, and the baby is expected to make his or her arrival in October.
The couple spoke out for the first time back in July when they granted an interview to Today. They warned other parents against the dangers of drowning.
They said something like that could happen in the blink of an eye and hopefully, their warnings would save other children. Read more about it here.
