Despite occasional productions derived wholly from the suggestions of very young children,[18] TEY tends to be created by adults and never features professional baby performers, although in the UK this is technically allowable under the UK Government’s The Children (Performances) Regulations 1968.[19] The presence of chaperones is universal, due to the obvious ethical impossibility of separating a very young child from all caregivers. Productions tend to be intimate in scale, with small audiences.[20] There is often no fourth wall in TEY, as actors are communicating with spectators throughout.[21] Multisensory experiences use sound, light, touch, smell and taste to engage with their audiences.[22] The needs of the very young, including feeding, sleep and going to the toilet, are carefully considered by TEY practitioners.[23]
