Answer

At 12 months and full-term (39 weeks), the CDC 1-year checklist is the one that applies — chronological age equals corrected age, so no age adjustment.

**1. What the CDC 1-year (75%+) checklist says for social communication and gestures**

- **Social:** Plays games with you, like pat-a-cake.
- **Language:** Waves bye-bye; calls a parent "mama" or "dada" (or another special name); understands "no" (pauses or stops).
- **Cognitive (adjacent):** Puts something in a container; looks for things you hide.
- **Fine motor (the pincer that supports pointing):** Picks things up between thumb and pointer finger.

eading your son against this card: **on** gross motor (pulls to stand) and **on track toward** language (babbling strings is the precursor to "mama/dada with meaning," but babbling alone does not yet meet the 12-month line). **Not yet meeting** at 12 months: waves bye-bye and pat-a-cake — the two items you named. Pointing is on the **15-month** card, so it is not yet a 12-month requirement, but it is the next gesture on the trajectory and worth noting.

The 75% line means "most children this age"; the checklist is family monitoring, not a screening result. ("Boys develop late" is a folk saying — CDC windows are not adjusted for sex.)

**2. Dated observation plan to bring to the visit**

| Date (2026) | What to write or do |
| --- | --- |
| Sep 17 | "12 mo, full-term (39 wk). Crawls quickly, pulls to stand, babbles strings (ba-ba). Does not wave bye-bye, play pat-a-cake, or point to ask. Mother concerned." |
| Day of visit | Hand the note above. Ask the pediatrician for a formal developmental screening — the CDC-cited example tool is the ASQ-3 — and ask for it at **this** visit, not the next. |

Have these CDC "share with the doctor" prompts ready, in your own words:
1. What do you and he do together? What does he like?
2. Anything he does or does not do that concerns you? — yes (waving, pat-a-cake, pointing).
3. Has he lost any skills he once had? — no.
4. Was he born prematurely or with special healthcare needs? — no (39 weeks).

I do not run screening or diagnose here. If the screening flags something, the next step is a formal evaluation by qualified clinicians — that is what decides the plan, not this chat.

**3. The single clarifying question**

The one answer that changes how this reads is whether he **brings a toy or object over to you just to show it, or looks to your face to check that you are watching what he is doing**.

Why this one: bringing/showing and checking your face are the joint-attention behaviours that sit underneath pointing. Present + two missing 12-month gestures → usually a slower tempo, and the visit + screening above is the right next step. Also absent → the screening request becomes more urgent, not less. That is the change that matters.

**Honest limits:** I can't tell from a description whether a 12-month-old is on track — that is what the ASQ-3-style screening and the clinician are for. The two dated items above are what to put in front of the doctor today.

Does he bring things to you to show them, or check your face to see if you are watching what he is doing?
