Detailed reference · Development

Surveillance now. Formal developmental screening later—unless concern changes the plan.

Social / emotional

Waves bye-bye; plays games such as pat-a-cake.

Language

Uses a special parent name; briefly pauses or stops at “no.”

Cognitive

Puts an object in a container; looks for a hidden object.

Motor

Scheduled surveillance

At 12 months

Developmental surveillance plus standardized parent-completed MEB screening.

Next formal screens

At 18 months

Routine standardized developmental and autism-specific screening. Do not wait when concern or regression is present.

Red flags requiring evaluation

No babbling or gestures; no response to name; loss of skills; not pulling to stand; no eye contact or social engagement; caregiver concern about hearing or vision. Failed milestones, regression, or concern warrant evaluation and possible formal screening or early-intervention referral.

Detailed reference · Recommended screening

Show the rule before the detail.

Routine, risk-based, timing-dependent, and uncertain recommendations are deliberately separated.

MEB screening

Routine

Standardized parent-report screening at 12 months under the 2025 AAP clinical report.

Timing, method & qualifiers

AAP timing: 6, 12, 24, and 36 months. Example tools include ASQ:SE-2 and BITSEA.

AAP 2025 [S7]

Iron deficiency / anemia

Check history

AAP timing is nutrition-specific within 9–18 months; individual risk may move testing earlier or add testing.

Timing, method & qualifiers

Human-milk-fed: 9–12 months. Formula-fed: typically 15–18 months after transition to cow’s milk. AAP prefers CBC plus ferritin; if unavailable, hemoglobin at minimum with reflex ferritin if abnormal. USPSTF: I statement for asymptomatic ages 6–24 months.

AAP 2026; USPSTF 2015 [S2][S3]

Lead

Risk-based

Universal at 12 and 24 months for Medicaid-enrolled children; otherwise jurisdiction- and risk-dependent.

Timing, method & qualifiers

Consider older housing in poor repair, high-prevalence area, known hazard, immigration/refugee status, and imported foods, cosmetics, or remedies. CDC blood lead reference value: 3.5 µg/dL. USPSTF: I statement for average- and increased-risk asymptomatic children.

CMS/Medicaid; Bright Futures; USPSTF 2019; CDC 2021 [S4][S5][S30]

Tuberculosis

Risk-based

Test only when exposure, travel, household, immune, or epidemiologic risk is present.

Timing, method & qualifiers

For children younger than 2, AAP guidance identifies TST as preferred and IGRA as acceptable.

AAP 2021 [S14]

Hearing

Check history

Surveillance and risk assessment at every visit; no routine objective hearing screen at 12 months.

Timing, method & qualifiers

Prompt audiology for risk factors or concern. Risks named include NICU stay longer than 5 days, family history, congenital CMV, craniofacial anomalies, and caregiver or clinician concern.

AAP 2023 [S9]

Vision

Routine

Examination-based assessment for all; instrument-based screening may be used when available at approximately ages 1–3.

Timing, method & qualifiers

Assess red reflex, fixation/following, pupils, and alignment. USPSTF: insufficient evidence below age 3; grade B for at least one screen at ages 3–5.

USPSTF 2017; AAP guidance [S10]

Oral health

Routine

Oral-health risk assessment; fluoride varnish after tooth eruption; dental home by age 1.

Timing, method & qualifiers

AAP/Bright Futures interval: varnish every 3–6 months, every 3 months when high risk. Fluoride supplementation depends on water fluoride status.

AAP 2020/2023; USPSTF 2021 [S11][S12][S13]

Development

Routine

Surveillance at 12 months; no routine standardized developmental or autism-specific screen at this visit.

Timing, method & qualifiers

AAP formal developmental screening: 9, 18, and 30 months. Autism-specific screening: 18 and 24 months. Evaluate immediately for concern or regression.

AAP 2020 [S6]

Caregiver depression & psychosocial needs

Check history

Formal postpartum-depression screening is scheduled at 1, 2, 4, and 6 months; no separate universal 12-month mandate was identified. Continue surveillance. Assess SDOH; formal tool choice varies by practice.

Detailed reference · Immunizations

Review the record first; then use the current schedule.

Verify minimum ages, intervals, products, contraindications, travel, and immunocompromise. The list below is intentionally not a replacement for the complete schedule.

MMR

Routine

Dose 1 at 12–15 months; minimum age 12 months. Travel can alter timing.

Varicella

Routine

Dose 1 at 12–15 months. Live vaccine; contraindicated in significant immunodeficiency.

Hepatitis A

Routine

Begin the 2-dose series at 12–23 months; dose 2 at least 6 months later.

PCV

Routine

Booster generally dose 4 at 12–15 months; product history and medical conditions can change the schedule.

Hib

Routine

Booster at 12–15 months; dose 3 or 4 depends on the product series.

DTaP

Check history

Ordinarily due at 15–18 months; may be given at 12 months if at least 6 months have elapsed since dose 3.

IPV & hepatitis B

Check history

Both have doses within a 6–18-month window; the record determines whether either is due.

Influenza

Check history

Annual for children 6 months and older; number of seasonal doses depends on lifetime influenza-vaccine history.

COVID-19 (2025–2026)

Guideline difference

AAP recommends vaccination for all infants and children 6–23 months without contraindications; CDC uses individual-based/shared clinical decision-making for people 6 months and older. Apply product- and history-specific guidance and keep the positions separate.

RSV prevention with nirsevimab

Risk-based

Monoclonal antibody, not a traditional vaccine. Eligibility depends on RSV season, age, prior protection, and qualifying risk for some children entering a second season up to 19 months.

MMRV first-dose disagreement

CDC/ACIP recommends separate MMR and varicella for dose 1 at ages 12–47 months unless the caregiver prefers MMRV. AAP 2026 expresses no preference, with counseling about the small increased febrile-seizure risk 1–2 weeks after MMRV. Preserve both formulations.

Detailed reference · Anticipatory guidance & lifestyle

Counsel for the child who is about to move everywhere.

Nutrition

Breastfeeding to 2 years or beyond when mutually desired; otherwise whole cow’s milk at 12 months. Prioritize iron-rich foods, varied textures, cup use and responsive feeding. Work toward bottle weaning by 12–15 months; avoid added sugars before 2 and limit juice after 1 to 4 oz/day.

Play

Encourage floor play, crawling, cruising, standing and walking practice. Limit unnecessary time in confining equipment. No structured daily exercise target is established for this age.

Sleep

Assess duration, routine and environment. Age ranges bridge infancy and toddlerhood: 12–16 or 11–14 hours per 24 hours, including naps. Continue safe sleep through 12 months.

Relationships & regulation

Responsive caregiving, positive discipline, predictable routines, reading, talking, singing and play. Normalize developmentally appropriate separation anxiety and stranger wariness; assess caregiver stress and support.

Exposure avoidance

Avoid tobacco/nicotine/e-cigarette exposure, impaired caregiving, and screen media before 18 months except video chatting. Assess lead, water and environmental toxin risks.

Injury & oral health

Rear-facing car seat; water supervision; poison, fall, burn and firearm prevention. Fluoride varnish after eruption, rice-grain smear of fluoride toothpaste, water-based supplement decision, dental home by 1.

Before the 15-month visit

Feeding transition, mobility childproofing, poison prevention, sleep routine, language-rich interaction, oral care, and low-screen daily life are the highest-yield anticipatory priorities.

Detailed reference · When routine care changes

Exceptions and evidence should be visible, not buried.

Prematurity / low birth weight

Risk-based

Use corrected age when appropriate; individualize iron, growth, nutrition, ophthalmology and related follow-up.

Development or growth concern

Risk-based

Assess and refer without waiting for the routine schedule; abnormal growth needs nutritional evaluation and closer follow-up.

Lead, anemia or TB risk

Risk-based

Apply the specific coverage, jurisdiction, exposure, feeding and epidemiologic rules described above.

Chronic disease / immunocompromise

Risk-based

Conditions can change growth, nutrition, vaccination, screening and referral; MMR and varicella are contraindicated in significant immunodeficiency.

Travel

Risk-based

May require accelerated vaccination; an MMR dose before 12 months for travel does not count toward the routine series.

Family psychosocial risk

Risk-based

Increase support and referral when caregiver mental health, substance use, IPV, food, housing or other needs affect the child.

Evidence conflicts retained

Do not silently merge these recommendations.

COVID-19

AAP universal recommendation for 6–23 months vs CDC individual-based/shared decision-making.

MMRV dose 1

CDC/ACIP preference for separate vaccines vs AAP no preference with febrile-seizure counseling.

Iron

AAP nutrition-timed screening and preferred CBC + ferritin vs USPSTF I statement.

Lead

CMS Medicaid requirement and AAP/Bright Futures risk/program approach vs USPSTF I statement.

Development

AAP scheduled universal screening vs USPSTF insufficient-evidence positions for selected asymptomatic screening questions.

Other uncertainties

New 12-month MEB recommendation; milk-fat choice at 12–24 months; caregiver-depression timing; instrument vision screening before age 3.
