And the TOWIE beauty shared an adorable snap of the newborn as they enjoyed a snow day together.
Taking to Instagram, Billie Faiers’ pal uploaded a photo of herself and the little one as they played in the garden.
“If kisses were snowflakes…I’d send you a blizzard,” she captioned the shot.
“Had to get a snap so I can show Sunday the first time she saw snow (well she was asleep but hey) #snow.”
Her 1.8million followers went into meltdown over the sweet upload, and rushed to praise the new mum.
“You and your baby are both so gorgeous @fernemccann you’re glowing,” one said.

“What a beautiful photo. Being a mummy really suits you and Sunday is just adorable xx,” a third commented.
While a fourth added: “Absolutely beautiful little princess! @fernemccann you’re an amazing mummy to your little angel and I’m sure she’s so proud of you… well done lovely, she’s beautiful like her mumma xxxxx.”
Ferne recently made headlines after making her first appearance on This Morning, following the birth of little Sunday.
And, during the appearance, the 27 year old opened up about life with her little one – vowing she did not want to be referred to as a single mum.
However, while many applauded the reality star’s stance, one person who wasn’t too impressed was Jessica Cunningham.
Taking to Twitter, the Apprentice runner-up admitted she felt frustrated over her words.
In a message posted to her 48.4k followers, she wrote: “On @thismorning yesterday, There was a well known celeb, stating she doesn’t want to be labelled a single mum as she is a first time mum.
“I felt frustrated by this, surely she is both? “We need to remove the stigma around this title.”
The mum of two then urged fans to help tackle the issue, adding: “Influencers can help to do this. #removethestigma.”
