👶 NCLEX Developmental Milestones: Infant Growth by Age
From head control to stranger anxiety, developmental milestones show up all over NCLEX pediatrics.
Knowing what babies can and should be doing at each age helps you spot normal vs abnormal development.
Today’s blog uses a KOTC visual chart and mnemonic to simplify the birth–12 months growth process.
📊 NCLEX Chart: Birth to 12-Month Milestones
| Age | Motor Skills | Language | Social Development |
|---|---|---|---|
| 2 Months | Lifts head, turns to sound | Cooing | Social smile |
| 4 Months | Rolls front to back | Babbles, laughs | Reaches for objects |
| 6 Months | Sits with support, transfers items | Consonant sounds | Stranger anxiety |
| 9 Months | Crawls, pulls to stand | “Mama/Dada” (nonspecific) | Peek-a-boo, waves |
| 12 Months | Walks with/without help | 1–2 words with meaning | Separation anxiety |
🧠 NCLEX Tip: Think “2-4-6-9-12”
Many NCLEX milestone questions use a timeline format — knowing what to expect at 2, 4, 6, 9, and 12 months helps you spot the outlier.
🩺 Nursing Implications
Educate caregivers on normal expectations
Track missed milestones at wellness checks
Encourage safe exploration (tummy time, play)
Know red flags (no sitting by 9 months, no words by 12)
