Sing songs or do fingerplay with toddlers and model gestures they can do with you while singing along or saying words.
Music provides a way for children to practise skills which are essential for interacting and developing relationships with others.
Making music does not require sharing, a skill most toddlers are still working on. Music-making can encourage positive peer interactions. It can also form the basis of toddlers' first friendships.
Music and finger rhymes also encourage imitation, turn-taking and self-regulation very naturally. These are crucial skills for effective interaction when building relationships with others.
