Brian Dowling's husband Arthur Gourounlian said he was "nearly crying" after the couple's daughter hit a major milestone.
Blake was born via surrogate last year and has brought the couple 'untold joy', however she's now teething - and isn't happy about it.
Taking to Instagram, the Dancing with the Stars judge, 42, said: "Oh my God I just put Blake to sleep and she broke my heart.
"She's been screaming since she had her dinner and I think there are four teeth, two here and two here, you can feel it and when I open you can see white dots. She is teething so much - do they scream and cry that much when they are teething? I feel like she was suffering and I don't know what to do.
"She doesn't cry, literally she does not cry anymore. Well, she only cries when she wants attention.
"But she was suffering and I didn't know what to do," he continued. "I was literally nearly crying with her. I hope she sleeps tonight."
After deciding he wanted to become a parent with Arthur, Brian, 44, enlisted the help of his younger sister Aoife who carried the “beautiful little baby” from an unknown egg donor.
Praising his “phenomenal” sibling, the presenter shared a picture of Aoife cradling baby Blake, with the caption: “Today was REUNION TIME in the Dowling Gourounlian household.
“We had a little visitor in the form of @effidy_dowling_️ It was an emotional reunion as the tears flowed. Times like this are so special.
“I still find it hard to believe that Aoife, Arthur and I created this BEAUTIFUL LITTLE BABY. Blake LOVES her Aunty Aoife so much and was so content in her arms.
“How SENSATIONAL does Aoife look especially only 5 days after giving birth.”
Husband Arthur replied to the post, gushing: “And of course, we managed to squeeze in a TikTok would have been rude not right WE LOVE YOU auntie Effidy.”
One fan said: “This does everything for my heart and soul such a selfless beautiful act, I'm super happy for you all Blake will be so loved.”
While another added: “Aoife is a legend........an absolute legend and mind her & hold her too. You guys rock, so happy for you & Blake you have all the love in the World. Congratulations everyone."
