The mother who invented the big gender reveal concept is now begging new parents to stop doing them immediately.
Jenna Karvundis, 39, from Pasadena, California came up with the idea of the surprise gender reveal by hiding pink icing in a cake and cutting into it to reveal they were having a girl.
However, in recent years gender reveals have become more elaborate, showy and even dangerous - and Mrs Karvundis now believes they're archaic and couples need to stop putting so much emphasis on their babies' gender.

In recent years gender reveals, loved by the Kardashians (pictured), have become more elaborate, showy and even dangerous - and Mrs Karvundis now believes they're archaic and couples need to stop putting so much emphasis on their baby's gender.
'Who cares what gender the baby is?' the mummy blogger wrote on Facebook.
'I did at the time because we didn't live in 2019 and didn't know what we do now - that assigning focus on gender at birth leaves out leaves out so much of their potential and talents that have nothing to do with what's between their legs.'
The mother-of-three said that the whole craze started after she posted on her blog about a party she threw 11 years ago when she was pregnant with her eldest child Bianca.
It was picked up and an interview with me was published in The Bump magazine and the idea kinda spread from there. I've got the article framed!' she said.
Candid: The mother of three opened up about her thoughts on the gender reveal craze in a Facebook post she shared on Thursday
'Anyway, I've felt a lot of mixed feelings about my random contribution to the culture. It just exploded into crazy after that. Literally — guns firing, forest fires, more emphasis on gender than has ever been necessary for a baby.'
In the photo that she shared, Jenna's two youngest daughters, Stella and Greta, are wearing frilly blue dresses while her eldest Bianca, 10, — who goes by Bee — looks as cool as can be in a light blue suit and sneakers.
'PLOT TWIST, the world's first gender-reveal party baby is a girl who wears suits!' the proud mother wrote.
The post has since gained more than 34,000 likes and more than 13,000 shares.
