Sisters' joint gender reveal ruined by cake mix-up

How did two sisters end up at the same gender-reveal party?

Mariana, 34, and her sister Ana Elisa, 33, discovered they were pregnant at almost exactly the same time and shared the same due date. They decided to celebrate together at a Thanksgiving dinner in Washington DC, where Ana Elisa lives. Their parents flew in from Brazil, and friends and family joined online via video call.

What went wrong on the night?

To keep the surprise, the sisters handed the ultrasound results to Ana Elisa's godmother — who is also Mariana's wedding godmother — and she passed the information to the baker. The baker mixed up the cake fillings. Both cakes came out pink when they were cut, leaving everyone confused. The godmother, watching on a video call, started shouting, but with microphones open and everyone talking at once, nobody could make out what she was saying.

How did they figure out the mix-up?

When they finally understood the godmother's explanation, it was clear the baker had swapped the cakes. There were small distinguishing details — Mariana's cake had two brown teddy bears (she was already a mother to Catarina, now 5) while Ana Elisa's had a lighter-coloured bear — but the swap happened anyway. The families took it in good humour, and the episode became a running joke. The baker later apologised and even offered a free jar cake.

How did the births turn out?

The sisters gave birth just 22 hours apart, both via natural delivery. Mariana had a boy, Mateus, and Ana Elisa had a girl, Serena — both now 2 years old. They recovered in adjacent rooms at the maternity ward. In a final twist, Mateus was born in the car on the way to the hospital. The video of the mix-up was only shared on social media recently, even though the event happened two years ago. Mariana is currently 32 weeks pregnant with her third child, Pedro.
