Lullabies. Simple, soothing… nonsense. Right? Wrong. Here we’re getting behind the importance of music and singing in a baby's development. India speaks to Dr Nina Polytimou about her research into how music can help with speech and communication and also be a powerful tool for bonding. India then visits a Singing Mamas group to hear how coming together as mothers to sing is a powerful, important, and missing slice of community. Kate Valentine, the founder, describes the impact it has on maternal mental health.
