The clip is almost three minutes long, and it gives a glimpse into how babies might react in their mother’s womb.
The bathing technique, called the Thalasso Baby Bath, was developed by a French woman called Sonia Rochel, and the video has collected more than 6 million views.
The video shows a pair of twins, a boy and a girl, as they embrace each other while receiving their first bath. The two were only a few days old when the filming was done.
Rochel says Thalasso Baby Bath was designed to imitate the conditions to which the children were accustomed in the womb.
