Attempts to soothe himself
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: Children self-soothe in different ways. Some suck their fingers or a pacifier; others cuddle a favorite object. Be attentive to how your child self-soothes and encourage the process.
