Sara Mullett is making a name for herself with songs guaranteed to send her audience to sleep.

Her collection of lullabies is causing quite a stir in the music business.

Sara and her music have been featured on Classic FM and her CDs are tipped for the top.

They have proved a real hit in Brighton and Hove book stores where 1,000 have been placed and are selling fast.

The soprano from Rottingdean put together a selection of the old favourites on two CDs including Twinkle Twinkle Little Star, Rock A Bye Baby and Hush My Baby, along with works by Mozart, Brahms, Chopin and Schubert.

One is in blue casing for boys and the other in pink for girls. Priced £11.99, they are called Lullaby Little Girl and Lullaby Little Boy.

As a young mother she found there was a shortage of good music for very young babies and few collections of lullabies.

Experts realise the importance of music in helping to stimulate the development of babies. Singing and playing music to them is believed to reduce stress and even help weight gain.

The calming effect of soft talking, soft lighting and soft music on the very young has been realised for centuries.

The former award-winning student from the Royal College of Music, who was selected to sing solo for a concert in honour of the Queen Mother, decided she could put together a good selection.

The 38-year-old mother of three children aged 12, ten and five, runs successful music schools in Rottingdean and Lewes. She tested some of the songs on her young pupils.

Sara said: "I was surprised there were no really good quality collections of lullabies available. There was electronic music designed to send babies to sleep but nobody singing the favourite lullabies.

"We then realised some of the words were for girls and the others for boys so we recorded one for each sex. These songs have been selected after I discussed which were the favourites with my music classes.

"Having a young family made it difficult for me to continue with my singing career so I started doing singing lessons from home.

"Now I am hoping my career will take off in a different direction."

The discs last for half a hour, which has been worked out as the time needed for a baby to fall into a deep sleep.

The harp accompaniment becomes slower on the final number especially designed for deep and long lasting slumber.

Ruth Calder, marketing manager of Borders Books, Churchill Square, said: "They have sold very well with us. I think Sara will do very well if her music is sold on a national or international basis.

"Young children do respond to music and visual things as the Teletubbies have proved. There could be a Teletubby effect with Sara's lullabies."
