At eighteen months, the toddler is just moving into what is commonly referred to as "the terrible twos." At this time in social development, the child is beginning to break away from the close contact s/he once had with primary caregivers. This is called differentiation and this "breaking away" is a critical part of social development that will influence the child's behavior throughout life. Expect lots of temper tantrums and what I call "touch backs." The child will want to be independent enough to explore the world, but will still need frequent "touch backs" with the primary caregivers in order to feel secure.
