A fascinating video shows a set of new𝐛𝐨𝐫𝐧 twins locked in a tender embrace with their eyes closed as they are bathed the very first time.

The two-minute 50-second long clip was uploaded to YouTube on November 8 by Paris-based midwife Sonia Rochel, and has since been watched almost four million times.

Ms Rochel made the clip public to showcase ‘The Thalasso Baby Spa’ – a small bath tub and shower unit she designed for babies to replicate the feeling of being in the womb.

At one point, water is carefully showered over their foreheads and eyes, while their noses and mouths remain above the surface so they can breathe with ease.

At the end of the clip the pair of infants are scooped out of the bath, placed on a mat and wrapped in towels to dry.

In an interview posted online last year, Ms Rochel – a grandmother of six – said she came up with the unique bathing method after taking a shower and realizing it felt great to have the water running on her face.

So she decided to try the technique with the new𝐛𝐨𝐫𝐧s and noticed it made them move like they do in the womb.

Ms Rochel has bathed twins together several times before and said she was not surprised by the infants’ reaction in the video.

Viewers have deemed her video ‘beautiful’ and ‘amazing’. One wrote: ‘I think [the twins] are just incredibly at peace here: warm water and very close to each other gives them the soothing feeling they endured for 40 weeks and what they are used to.’

Another woman said the video made her feel broody. ‘Amazing, makes me want to make a 𝑏𝑎𝑏𝑦.’
