This is the child's ability to interact with others, including helping themselves and self-control. Examples of this type of development would include: a six-week-old baby smiling, a ten-month-old baby waving bye-bye, or a five-year-old boy knowing how to take turns in games at school.
TIP: It is never to early to establish a habit of speaking softly and gently to your child. Your newborn will sense the stability you communicate.
