When children develop normally

There are large variations in the way children develop. But there are some characteristics in physical, language and emotional development that all children have in common. Table 17.1 and Figure 17.2 present some important developmental milestones (significant events in development that are achieved by most children around a particular age) in early childhood. The exact age by which these milestones are achieved varies from child to child, but when there is a serious deviation from these typical developmental milestones, there is reason for concern. In the following sections we will discuss a few important conditions in which the typical development is delayed or abnormal.

Table 17.1 Normal childhood developmental milestones.

Age | Physical development | Language development | Emotional development
0–1 years | 4 months: sits with support 8 months: stands 9 months: crawls | 4 months: laughs aloud 8 months: repetitive responding 10 months ma-ma, ba-ba | Issues of trust are key 9 months: stranger anxiety; exploratory and solitary play 10 months: plays peek-a-boo
