Our position is that effective teaching of young children necessitates physical contact. Every child benefits from positive and nurturing touch. Children need to be cared for by adults (not robots) who are responsive to their emotional needs.
Additionally, infants and young children can need assistance with nappy changes and toileting, first-aid treatment when they are hurt, and other forms of physical assistance to assist them to develop new skills and confidence e.g. holding an adult's hand while they are walking along a plank above the ground and learning to balance.
