Independent Living Unit 3 Practice Test

Understanding the word no signals a child’s receptive language development and their grasp of social cues. When a baby begins to understand no, they’re not just making sounds—they’re recognizing that a spoken word carries a consequence and indicates they should stop or change behavior. This typically emerges around 9 to 12 months and helps with safety and self-regulation, laying the groundwork for following simple instructions.

The other options involve different kinds of development. Dressing self shows early self-care and fine motor skills, peek-a-boo is about social play and object permanence, and toilet training reflects emerging independence and bladder/bowel control. While important, none specifically demonstrates understanding the meaning of a word like no.
