Why regular home development checks matter
Watching your baby's skills grow is one of the clearest ways to spot problems early — when interventions have the biggest effect. This article gives a short, doable plan for monthly informal checks during the first 6 months, plus suggested focus items for a 3‑month and a 6‑month screening activity you can do at home. Use these checks to notice patterns, collect examples, and bring concrete notes to your child's pediatrician or early‑intervention team.
Professional guidance recommends routine developmental surveillance at every well‑child visit and standardized screening at set ages; these home checks are meant to complement — not replace — formal screening and pediatric care. For example, the American Academy of Pediatrics (AAP) advises administering standardized developmental screening tests at key well‑child visits (including the 9‑, 18‑, and 30‑month visits) and recommends autism screening at 18 and 24 months.
Free milestone checklists (birth to 5 years) and parent resources are available from public programs to help you know what to expect each month. Use the short activities below to track progress and build a simple record you can share with your provider.
Monthly informal checks (first 6 months) — a 5‑minute routine
Do these short activities once a month (or whenever you notice a change). Keep a one‑page log with date, what you saw, and one quick note:
- Social & language: Does baby smile back or make different cries? Try face‑to‑face cooing for 1 minute and note responses.
- Eye contact & tracking: Move a colorful toy slowly side to side — does baby track with their eyes or head?
- Gross motor: During tummy time, can baby lift and turn their head? At 4–6 months, do they push on forearms?
- Fine motor: Offer a small toy — can baby grasp and hold, bring it to mouth, or transfer between hands?
- Feeding & state: Note feeding patterns, strong gagging, or persistent difficulty coordinating suck‑swallow‑breath.
If you prefer a validated parent questionnaire, many programs use Ages & Stages (ASQ) and related tools — ASQ guidance supports screening every 4–6 months in the first two years when possible. These monthly home checks are shorter than an ASQ but help you spot change between scheduled formal screenings.
3‑month and 6‑month focused checks — what to test and why
At roughly 3 months and again at 6 months, do a slightly deeper check (10–15 minutes) that covers four areas: motor, communication, social‑emotional, and sensory/feeding. Below are quick, observable items you can try at home.
3‑Month focused items
- Head control: When held upright, baby briefly steadies head.
- Social smile & cooing: Baby smiles responsively and makes vowel sounds.
- Visual tracking: Follows a toy across the midline smoothly.
- Hands to midline: Brings hands together and may reach for objects.
6‑Month focused items
- Sitting support: Sits with minimal support or propped on hands.
- Rolling & strength: Rolls from tummy to back, pushes weight through arms.
- Babbles and responds: Babbles consonant sounds and responds to name more often.
- Transfers & grasp: Picks up small objects, transfers them between hands.
These milestone examples align with public milestone resources and validated screening tools. If you see repeated absence of expected skills (for example, no social smile by 3 months, no babbling by 6 months, or poor tracking), share your notes with your pediatrician. Formal screening tools like ASQ are designed to be used at set intervals and can flag areas needing evaluation.
Quick red flags to act on now (contact your pediatrician or urgent care): no breathing or feeding well; floppy or very stiff baby; no social smile by 3 months; does not track objects or respond to loud sounds; any sudden loss of skills. These signs require prompt medical review.
Putting checks into practice: tracking, screening tools, and next steps
How to make this easy:
- Keep a single page log: Date, 3 quick observations, and one short video (10–20 seconds) if something concerns you.
- Use validated questionnaires: When possible, complete an ASQ (or the clinic’s recommended screener) at regular intervals — many programs space ASQ administration roughly every 4–6 months for infants. Ask your pediatrician for copies or use free public milestone checklists before visits.
- Bring examples to visits: Show your one‑page log or video at the well‑child visit; concrete examples help clinicians decide whether referral or formal evaluation is needed.
- Referrals & Early Intervention: If your provider has concerns, Early Intervention (EI) services can evaluate children under 3. Early referral is associated with better outcomes — don’t delay because you’re unsure. The AAP and screening resources emphasize timely referral and follow‑up when screening flags concerns.
Summary: short monthly checks plus a focused 3‑ and 6‑month routine help you notice change, collect clear examples, and partner with your pediatrician. Use validated screeners (ASQ/M‑CHAT when recommended) for formal checks, and seek help promptly for red flags — early action matters.
