新手爸妈最常问的问题之一:到底该多久给宝宝称一次体重、量一次身高?答案取决于孩子的月龄——掌握好频率,才能及早发现生长问题。

WHO 推荐的监测节奏

对于健康儿童,世界卫生组织建议按以下频率进行监测:

月龄 建议频率 关键指标
0–6 monthsEvery 2–4 weeks年龄别体重、年龄别身长
6–12 months每月年龄别体重、年龄别身长、头围
1–2 yearsEvery 2–3 months年龄别体重、年龄别身高、BMI
2–5 yearsEvery 6 months年龄别身高、身高别体重
5–19 years每年年龄别 BMI、年龄别身高
重要提示:如果宝宝是早产儿或有健康问题,儿科医生可能会建议更频繁地监测。请始终遵循医生的建议。Important: If your child was born premature or has a health condition, your paediatrician may recommend more frequent monitoring. Always follow their guidance.

如何在家准确测量

体重:2 岁以下婴儿请使用电子婴儿秤。为了让数据可比,每次都在一天的同一时间、裸称测量——最好在早上喂奶前。Weight: Use a digital baby scale for infants under 2 years. Weigh your baby naked at the same time of day for consistency — ideally in the morning before feeding.

身长(2 岁以下):让孩子平躺测量(卧式身长),使用硬质测量板或软尺贴合平面测量。这需要两个人配合——一人固定头部,一人轻轻拉直双腿并对齐脚跟做标记。Length (under 2 years): Measure lying flat (recumbent length) using a rigid measuring board or a soft tape against a flat surface. This requires two people — one to hold the head, one to extend the legs and mark the heels.

身高(2 岁以上):靠墙站立,双脚并拢,脚跟、臀部和头部贴墙。用一本平放的书在头顶做标记,再量到地面。Height (2+ years): Measure standing against a flat wall with feet together, heels, buttocks, and head touching the wall. Use a flat book on the head as a marker and measure to the floor.

什么时候需要担心?

出现以下情况,请联系儿科医生:
