Our son just had his 18-month birthday.
Ask
Our son just had his 18-month birthday. At home, he communicates quite well for things he wants — if he wants milk or a snack on the counter, he reaches his index finger toward it and makes a vocalization ("uh! uh!"). If a toy is stuck, he takes my hand and leads me to it.
However, yesterday during a playgroup, I noticed other 18-month-olds pointing up at airplanes in the sky or pointing at a dog across the park, looking back at their parent to say "look at that!" My son almost never does this. He doesn't point to show me things just for the joy of sharing attention — he only points when he wants an object (requesting).
I read that the CDC 18-month milestone specifically says "Points to show you something interesting."
Could you help us evaluate this:
1. **CDC 18-month milestone criteria**: Does "protoimperative pointing" (pointing to request an item) satisfy the CDC 18-month milestone, or does the milestone specifically require "protodeclarative pointing" (pointing to share interest/joint attention)?
2. **Joint attention markers**: Beyond pointing, what other joint attention behaviors are expected around 18 months (e.g., following a parent's point, bringing toys to show, referencing faces when unsure)?
3. **Home facilitation**: What daily interaction routines or games can we play over the next 4–6 weeks to encourage pointing to share interest?
4. **Pediatrician screening prep**: At the 18-month well-child visit (M-CHAT-R screening), how should we describe this distinction accurately to our pediatrician, and when is an Early Intervention evaluation warranted?
Answer
You're reading the card correctly. The CDC 18-month social item is "Points to show you something interesting" — that's the sharing form (what your sources call protodeclarative; the card just says "show"). Your son's index-finger + "uh uh" to ask for milk is the requesting form (protoimperative). By the wording on the card, requesting alone doesn't tick this row.

One missing checklist item isn't a diagnosis — it's the right reason to bring a dated observation to the 18-month well-child visit and ask for a formal developmental screening.
**What else on the 18-month card is relevant here**
- "Moves away from you, but looks to make sure you are close by" — checking-back
- "Looks at a few pages in a book with you" — shared book reading
Beyond the card, the usual joint-attention markers around this age: follows your point or gaze, brings a toy to show you (not just to hand over), glances at your face when something is new, alternates gaze between an object and your face.
**Everyday play ideas (4–6 weeks)**
These are general caregiver practices, not a therapy plan. If after a month nothing has shifted and you're still concerned, that's information for the doctor — not a verdict either way.
- **Child-led play**: sit on the floor, let him pick the activity, comment on what he's already looking at.
- **Pause-and-wait**: during play or a book, pause 5–10 seconds. Many children will point, look, or vocalize to restart the interaction.
- **Comment, don't question**: name what he's holding ("a red truck, going fast") rather than asking "what's that?"
- **Model the sharing form**: when you see something interesting — a bird, a plane, a dog — point, look at him, and say "look, a bird!" Many times a day; copying is more likely than being told.
- **Picture books**: short board books, face-to-face, let him turn pages. This is on the 18-month card.
**For the 18-month visit**
The visit typically includes the M-CHAT-R/F — a parent-report screener, not a diagnosis. A positive screen leads to a structured follow-up interview; persistent concerns lead to a formal developmental evaluation by qualified clinicians. That evaluation, not the M-CHAT-R score, is what decides whether support is offered.
Dated observations carry more weight than conclusions. Try lines like:
- "Since about 16 months, he points with his index finger and vocalizes to ask for things he wants. He doesn't yet point to show us interesting things like a plane or a dog."
- "He leads us by the hand to a stuck toy and back — intentional communication."
- Gestures he uses: index-finger request point, hand-leading. Not yet seen: declarative pointing, showing-to-share, following our point.
- No skills lost. Hearing check status. Words or word-attempts across every language used at home.

Where are you based? The post-evaluation support programme is country-specific — state Early Intervention in the US (under 3), the early-intervention reporting system in Taiwan, early-support services in Germany — and that part depends on where you live.
