“When” questions are among the later wh-questions children learn, typically emerging after “what,” “where,” and “who.” Because they require an understanding of time, they present a unique challenge in speech therapy. Most children begin using “when” questions reliably between ages 3 and 4, but children with language delays or autism spectrum disorders often need targeted support to master them.
Why “When” Questions Are Harder Than Other Wh-Questions
Children acquire wh-questions in a fairly predictable order. “What” and “where” come first because they ask about concrete, visible things: objects and locations a child can point to. “Who” follows shortly after. These three are sometimes called wh-pronominals, and they tend to appear alongside simple verbs like “is” and “are” before age 3.
“When,” “why,” and “how” belong to a more complex group that researchers call wh-sententials. These questions ask about abstract concepts you can’t see or touch. Time, in particular, is invisible. A child answering “Where is the ball?” can look around and point. A child answering “When do we eat breakfast?” has to retrieve a concept (morning) that isn’t present in the room. This is why “when” questions sit later in the developmental sequence and why they often become a specific therapy target.
Typical Age Range for “When” Questions
Typically developing children understand basic wh-questions (what, where, who) by around 20 to 32 months of age, and they start producing those questions by 27 to 29 months. “When” questions come noticeably later. Most children begin comprehending and using “when” between roughly 36 and 48 months, though there’s natural variation. If a child older than 4 consistently struggles to answer simple “when” questions about daily routines, that’s a common reason a speech-language pathologist would add this skill to their therapy goals.
Prerequisite Skills Children Need First
Before a child can answer “when” questions, they need a foundation of temporal vocabulary, the words and phrases that describe time. Without these building blocks, the question itself doesn’t make sense to them, even if they understand the grammar.
Key temporal concepts to build first include:
- Basic time words: today, tomorrow, yesterday, now, later, soon
- Sequence words: first, then, next, last, before, after
- Parts of the day: morning, afternoon, night, bedtime, lunchtime
- Routine anchors: connecting events to familiar activities (“after lunch,” “before bed,” “when it’s dark”)
Children also need a solid grasp of “what” and “where” questions before moving to “when.” If a child can’t reliably answer “What do you wear on your feet?” they’re not ready for “When do you wear a coat?” Therapy typically follows the natural developmental order, building from concrete to abstract.
Functional “When” Questions Used in Therapy
Therapists often start with “when” questions tied to a child’s daily routines, because these connect time concepts to experiences the child already knows. The answer doesn’t require clock-reading or calendar skills. Instead, the child links the question to a familiar situation. Examples that work well at early stages include:
- When do we sleep? (at night)
- When do we eat breakfast? (in the morning)
- When do we use an umbrella? (when it’s raining)
- When do we wear a coat? (when it’s cold outside)
- When do we put on a bandaid? (when we’re cut)
- When do we wear sunglasses? (when it’s sunny)
- When do we turn on a flashlight? (when it’s dark)
- When do we wear a seatbelt? (in the car)
Notice that the expected answers fall into two categories: time of day (“in the morning,” “at night”) and situational conditions (“when it’s raining,” “when it’s cold”). Starting with situational answers is often easier because the child can picture a concrete scenario. Time-of-day answers require slightly more abstract reasoning.
Teaching Strategies That Work
The most effective approach combines visual supports with a clear prompt hierarchy, gradually reducing help as the child gains confidence.
Visual Supports
Visual cue cards are a staple of wh-question therapy. A typical set includes individual cards for who, what, where, when, why, and how, each paired with an image that represents the category. For “when” questions, the visual is usually a clock or calendar icon. These cards serve as a constant reminder of what type of answer is expected. Some therapists use a visual strip that lines up all the wh-words in a row so the child can reference them during activities. Others use leveled resources: Level 1 provides the visual plus answer choices the child can select from, while Level 2 removes the choices and asks the child to generate an answer independently.
Prompt Hierarchy
A typical progression moves through these stages:
- Full model: The therapist asks the question and immediately provides the answer. “When do we sleep? At night. When do we sleep?” The child repeats “at night.”
- Forced choice: “When do we sleep? In the morning or at night?” The child picks the correct option.
- Sentence starter: “When do we sleep? At…” The child completes the phrase.
- Independent response: The therapist asks the question with no support, and the child answers on their own.
Moving through these levels too quickly is a common pitfall. Children need repeated success at each stage before the support is pulled back. For “when” questions specifically, the forced-choice step is particularly valuable because it teaches children what category of answer is appropriate. Many kids who struggle with “when” give a “where” or “what” answer instead, simply because they don’t yet understand that “when” is asking about time.
Sorting and Categorizing Activities
Having a child sort picture cards into time-based categories (morning activities vs. nighttime activities, winter vs. summer) builds the temporal reasoning that “when” questions depend on. Once the child can sort reliably, the therapist reframes the task as a question: “You put swimming in the summer pile. When do we go swimming?”
Practicing “When” Questions at Home
Carryover outside of therapy sessions makes a significant difference in how quickly children master this skill. The good news is that daily routines are full of natural opportunities to practice.
During meals, bath time, and bedtime, you can weave in simple “when” questions that match what’s already happening. “When do we brush our teeth?” while standing in the bathroom gives the child environmental cues to support their answer. Over time, ask the same questions outside of context, like during a car ride, to see if the child can retrieve the answer without visual reminders.
Reading together is another strong opportunity. When you finish a page in a storybook, pause and ask a “when” question about what just happened. “When did the bear go into the cave?” Keeping a visual bookmark with wh-question reminders tucked into the book can prompt you to ask a variety of question types during reading, not just “what” and “who,” which parents tend to default to.
Worksheets and structured homework from the therapist also help, but the conversational practice during real routines is what drives generalization. A child who can answer “when” questions on a worksheet but not in conversation hasn’t truly mastered the skill yet. The goal is for the child to recognize and respond to “when” questions wherever they come up naturally.
Signs of Progress to Watch For
Early on, children often answer “when” questions with the wrong type of response, giving a location instead of a time, or naming an object. This is normal and expected. The first sign of progress is when the child consistently gives a time-related answer, even if it’s not perfectly accurate. “When do we eat breakfast?” answered with “after sleeping” shows the child understands the question type, even though “in the morning” would be more precise.
The next milestone is answering without visual supports or prompts. After that, look for the child to start asking their own “when” questions spontaneously: “When are we going to the park?” or “When is grandma coming?” That shift from answering to asking signals the child has internalized what “when” means and can use it as a real communication tool.
