It has been defined as “professional theatre led by adults performing for an audience of babies from months old to toddlers approximately one and a half to two years old accompanied by a parent or adult companion. Babies usually sit on their caregiver's lap or in a stroller, and watch a play - usually between 30 to 45 minutes long - designed especially for them”.[1] In addition, performances for newborns, centring on bonding and attachment, and more participatory productions which invite children to enter the performance area for a time[2] have become common. Even productions aimed at foetuses and expectant mothers have been created.[3]
