The “womb song” classes are intended to boost language skills in infants and also help mothers develop a closer bond with them.
Women who attend the classes are taught how to sing a range of songs including rounds and lullabies – although not nursery rhymes.

Maya Waldman, who runs the project, said: “The repertoire is a selection of quite simple and inspiring songs from around the world. They are quite soulful, some are uplifting and some relaxing.
“One of the goals is increasing the chance of people singing to their children.”
The Womb Song workshops, which started in January for women booked into the maternity unit at Chelsea and Westminster NHS foundation trust in west London, are based on the idea that unborn babies respond to music and their parents’ voices.
