- Cannot understand “no” or “Danger”
- Watches people, objects, and activities in the immediate environment.
- Shows awareness of distant objects (15 to 20 feet away) by pointing at them.
- Responds to hearing tests (voice localization); however, loses interest quickly and, therefore, may be difficult to test informally.
- Follows simple instructions.
- Reaches for toys that are out of reach but visible
