Due to natural variation, individuals pass through the Tanner stages at different rates, depending in particular on the timing of puberty.Among researchers who study puberty, the Tanner scale is commonly considered the "gold standard" for assessing pubertal status when it is conducted by a trained medical examiner.

Constitutional growth delay: Benign variant of normal height growth due to a delay in the onset of puberty. Expect a delayed bone age and a trajectory that is not on track for the target height. Endocrine disorders: Pathologic variant of normal growth due to hormonal abnormality. Expect a delayed height trajectory accompanied by a gain of weight.
The greatest circumference of the head, which corresponds to the plane of the occipitofrontal diameter, averages 34.5 cm (13.6 in), a size too large to fit through the pelvis without flexion. The smallest circumference, corresponding to the plane of the suboccipitobregmatic diameter, is 32 cm (13 in).
The way to measure a baby's length is to lay the baby down and stretch a measuring tape from the top of the head to the bottom of the heel. Weight In developed countries, the average birth weight of a full-term newborn is approximately 3.4 kg ( 7 + 1 ⁄ 2 lb), and is typically in the range of 2.7–4.6 kg (6.0–10.1 lb).

[16] [17] [18] The heritability of birth weight ranges from 25 to 40%. [19] [20] There is a complex relationship between a baby's genes and the maternal environment that the child is developing in. [21] Foetal genes influence how the fetus grows in utero, and the maternal genes influence how the environment affects the growing fetus. [17]
