The influencer Lizzie Kieffer shared the unfathomably tragic news that her 12-month-old daughter had died this week.

Kieffer — a physical therapist and social media star — revealed in a heartbreaking Instagram post that she and her husband Matt Kieffer were ‘shattered’ by the mysterious death of their daughter Lilian ‘Lily’ Louise Kieffer.

In the tender post, she revealed that her youngest child had been suffering from a ‘large mass on her brain’ that had previously gone undetected.

Kieffer, who is currently pregnant with her third child, also shares an older daughter named Mia with her husband. 

Her daughter Lily died less than 10 days after celebrating her first birthday. 

‘We are shattered,’ she began her devastating announcement. ‘Wednesday we woke up to a nightmare that we never could have ever imagined becoming our reality. Our Lily passed away.’

‘Our hearts, our bodies, our souls ache for her as she was the purist [sic] of beings and brought light to every single space she filled,’ Kieffer continued. ‘Our days are written before we were even formed, and in Lily’s 374 days of life, she taught us more than I think many could in their lifetime.’

She wrote that the family ‘don’t have answers’ as to what happened to their daughter, nor could she explain why her death was ‘God’s plan’ for their lives. 

‘And we will never fully understand this mystery until we see her again one day,’ she continued. 

However, she expressed certainty that her late daughter was with ‘loved ones in heaven,’ and she sweetly added that Lily was ‘probably playing in her ball pit or riding in her little red car up there.’ 

‘We feel her,’ she wrote. 

‘We also have come to learn that Lily had a large mass on her brain that we could have never known about as she never showed signs,’ Kieffer continued, adding that additional answers could take ‘months’ while additional tests were conducted.

‘Our family and friends are holding us when we don’t feel it’s possible to move,’ she continued, before adding that she and her husband ‘feel God’s presence around’ them. 

Kieffer asked her fans and followers to ‘pray hard’ for her family in their difficult time. 

Just days before Lily's death, Kieffer shared a sweet video of herself playing with the little girl and her old sister Mia. 'Being in the front row seat to their life is my greatest honor,' she wrote at the time
