"Wow another perfect, beautiful boy!!! Congratulations," a follower of Morgan's commented.
"Gorgeous! Huge congratulations. As a mother of 3 boys, I can tell you that it is the best! Wouldn’t swap any of them for a million girls. Enjoy 💙💙💙," another said.
"Awww congratulations to you all ❤️ he is just beautiful 😍 you make the most beautiful babies ✨," a delighted third person wrote.
But it was Morgan's mum Lisa who had fans welling up with her own sweet tribute to her newest grandson in the comment section.
"Morgan my beautiful 😍… look at your gorgeous little family. I love you all so much and Jaimi would so love this too xxxxx" she penned.
Jaimi Lee Kenny, Lisa and Grant's eldest daughter, died suddenly in 2020 following a long health battle but her family have worked hard to keep her memory alive.
Morgan has played a big part in that, joining in family memorials and celebrations, as well as supporting her parents through the tragedy.
While Lisa and Grant are no longer married, both have close relationships with Morgan and their grandchildren.
Morgan announced her pregnancy in November last year, taking to Instagram to share a sonogram image and a mirror-selfie of her burgeoning bump.
“Life is crazy – we might as well stay in the crazy!” she wrote.
“Baby #3 due end of May.”
Lisa Curry commented on the post, sharing her excitement.
“My beautiful baby girl 😍😍 So happy for you and you're a beautiful family. Crazy grannie to the rescue when you need xxx," she wrote.
The new arrival is Morgan’s third child with Ryan, who she met in high school and married in 2016.
The couple gave birth to their first son, Flynn Melchior Gruell, in March 2018.
Taj Grant Gruell, their second son, came along in November 2020, shortly after the family lost Morgan’s sister, Jaimi after she suffered from a long-term illness, which has been an ongoing source of grief for the family.
After Jaimi’s passing, Morgan took to Instagram to share her thoughts, writing “I am grateful that Flynn got two and a half years with his Aunty”.
“I am so grateful for the time that I had you as my big sister.”
Morgan has worked as a dancer for most of her career, but also teaches barre classes and Pilates, offering classes to new mothers who can bring their babies along.
She now also runs Mum Bum, a maternity and activewear brand for mums in all stages of pregnancy.
Congratulations to Morgan, Ryan, and their beautiful family!
