As well as classical CDs and DVDs for very young children, this week sees the launch of a programme of concerts for babies - including those in utero.
Does playing classical music to babies make a difference? Opinion is divided; but many experts think that it may stimulate the brain in a way that helps educational and emotional development.
It's known as the Mozart Effect, a theory which is credited with boosting IQ, improving health, strengthening family ties and even producing the occasional child prodigy.
Numerous studies conclude that playing music to babies in the womb and in the early years helps build the neural bridges along which thoughts and information travel. And research suggests it can stimulate the brain's alpha waves, creating a feeling of calm; a recent study of premature infants found that they were soothed by the music.
In Florida, all state-funded pre-schools are required to play classical music by law, and many US hospitals give classical CDs to new mums.
In the UK, many parents have also embraced the theory, with Classic FM's Music for Babies CD enjoying several weeks at the top of the classical charts earlier this year.
