嬰兒的發展里程碑（Developmental Milestones）具有一定的順序性。4 個月大的嬰兒在俯臥時應能支撐頭部並維持穩定（Head Control）。若此時頭部仍無法穩定控制，代表頸部肌肉張力或神經發育可能存在問題，屬於臨床上的「紅旗警訊（Red Flag）」，必須進行進一步的神經學或小兒科評估，排除發育遲緩或肌張力低下等狀況。
By four months of age, infants should have achieved head control; inability to hold the head steady is a red flag for potential neuromuscular or developmental issues requiring further evaluation. Other findings, such as lack of stranger anxiety or delayed rolling, are within normal limits for this age group.
