Bradley died aged six in July 2017 after a long and brave battle against the rare type of childhood cancer.
His cheeky smile and never-ending cheerfulness were an inspiration to so many, with his spirit continuing to support families today through the charity foundation.
Gemma and Carl said in the post: “She is an absolute dream and we couldn't be happier right now.
“She has changed so much since she was born, we did try and get some nice photos last night in her vest but she had other ideas.
"She is camera shy just like her oldest brother Kieran, and nothing like Bradley he absolutely loved his photo being taken."
The family added they were taking Gracie-Mae to the Stadium of Light where Bradley loved watching Sunderland for their match against Ipswich on Saturday afternoon.
They held off sharing pictures until all of the family got to meet her first.
Gemma and Carl added: "Thank you to everyone that has sent me well wishes, cards and presents it is really appreciated.”
One friend commented on the pictures: "Congratulations..she is gorgeous.. Bradley will be looking down on his beautiful little sister.”
One said: “Adorable just like her brother x”, while another said she was a: “Perfect little bundle of joy. So like her brothers, gorgeous xxx.”
Gemma and Carl revealed in May that they were expecting their third child after trying from the start of the year.
Gemma said then: “Bradley is going to be the best guardian angel to his little brother or sister.”
