Which behavior indicates that a 19-month-old child is not meeting developmental milestones?

The behavior of a 19-month-old child watching television for 6 hours a day is indicative of not meeting developmental milestones. At this age, children are typically encouraged to engage in interactive play, physical activity, and exploration of their environment. Excessive screen time, especially to the extent of several hours a day, can impede social, cognitive, and physical development, leading to delays in language acquisition, social skills, and sensory experiences that are vital at this stage.

In contrast, enjoying play with blocks supports fine motor skills and creativity, engaging in parallel play with peers helps develop social skills through observation and interaction, and being able to feed oneself with a spoon is a sign of growing independence and motor skill development. These behaviors align with expected developmental milestones for a child approaching 2 years of age.
