The post featured photos of the couple and the infant, along with the message, "After a noticeable decrease in movement we found out her heart had stopped beating."

"Words cannot describe our pain of this loss or our happiness at being able to spend time with our daughter. She is absolutely beautiful, with blonde lashes and brows and a little smile for mom and dad. The love we feel for her is overwhelming. The grief we feel will be with us forever but so will the love."

They went on to explain that with the baby's death, all of their "hopes and dreams for her have been taken away," but they were looking forward to spending time "with her again" eventually.

The couple also posted pictures of their 3-year-old son Stormur cuddling up with Grace in a blanket.

They concluded, "Her spirit lives on through us and her siblings. We ask that you respect our privacy at this time as we grieve this unbearable loss. Thank you all for any kind words and support."

According to the NHS, "A stillbirth is when a baby is born dead after 24 completed weeks of pregnancy. It happens in around 1 in every 200 births in England. If the baby dies before 24 completed weeks, it's known as a miscarriage or late foetal loss."
