Influencer Lizzie Kieffer is opening up about the difficult holiday season following the death of her 12-month-old daughter Lily. "We imagine His birthday party was glorious this year up in heaven. Mia is convinced Jesus and Lily shared an Elsa birthday cake...and Lily had frosting all over her face," Kieffer wrote via Instagram on Saturday, December 27, alongside a slew of pictures featuring her late daughter. "I knew the holidays would be tough, but they have been so much harder than I thought," she continued.
