Sophie Cachia has changed her baby daughter's name.

Mummy blogger Sophie Cachia has announced on Instagram that she has changed her baby daughter’s name, two weeks after giving birth.

Betty Margaret Cachia was born on January 14, but on Saturday afternoon the blogger wrote from the perspective of her two-year-old son, Bobby, saying both her and husband Jaryd had “f*cked up”.

“So y’all want to hear a funny story? My mum & dad fucked up. Like, bayyyyyyd. Mum was all drugged up and hormonal and started to doubt my sissy’s name as soon as she was born,” she began.

However, within days, Cachia said she had changed her tune and fell back in love with the name Betty.

“That was until Daddy came along and dropped the bomb on us both that he started to doubt the choice too. LOLZ. Good one Dad.”

She went on: “It wasn’t that they didn’t LIKE the name anymore, something about her chubby cheeks not suiting it and the feel just wasn’t right. So I’ve been given the gig today to formally RE-introduce my little sister. Mum & Dad say her name is apparently Florence, but me being the boss two year old I am, have chosen to nickname her Flossy which is really sticking.”

Although Cachia acknowledged this happens to parents “all the time”, it was a little bit more difficult having to inform 250,000 of her followers.

She also revealed the couple changed the name when Betty was only eight days old, but wanted to give Bobby the chance to get his head around the name before they announced it publicly.

Another welcome to the world, Florence Betty Margaret Cachia.
