A. A 2-year-old toddler should have more than six teeth by this age, and the eruption of only six teeth is a delay in expected development. Most children have 16 teeth by age 2. B. Using two- or three-word phrases is appropriate for a 2-year-old and is a sign of normal language development. C. Building a tower of six to seven cubes is an appropriate developmental milestone for a 2-year-old and indicates normal motor development. D.
