The Edge's Sharyn Casey shares first baby pic

The Edge host Sharyn Casey has introduced her baby to the world with a beautiful photo on Instagram.

After speaking out about suffering multiple miscarriages, Sharyn emotionally announced her successful pregnancy on air in August, 2017.

On Friday, she uploaded posted a touching message along with the photo of her, the baby and her The Rock host husband Bryce.

"He's here! Our Little Bug Tyson Lloyd Casey arrived yesterday and we are so in love!" writes Sharyn.

"[I] want to say a HUGE thank you to our incredible [obstetrician] Dr Ammar Al-Abid, who fixed my uterus 18 months ago so our baby dream could come true. To Rene Schliebs, our fertility naturopath and our midwife Denise Johnson for being such an incredible support, along with our family and friends.

"We feel ridiculously lucky."

Bryce posted his own message and photo on Instagram, too.

Both Sharyn and Bryce opened up on air when they announced the pregnancy last year, sharing their struggles with fertility.

On the official The Edge Instagram account, the radio station says it is "so proud and excited" by the news of the birth.
