Morgan Miller shared a photo on Instagram on Friday showing herself weeping as she held 19-month-old Emmy, who was hooked up to wires and tubes in the hospital.
Miller writes that she wishes she could have one more day to hold her daughter and that she'll continue to spread awareness about childhood drownings.
She says the girl's footprint "will forever be left on this world."
The Millers spoke about their daughter's death on NBC's "Today" show last month, describing how they found the little girl floating in a neighbor's pool.
The girl died the next day on June 10.
