Human Growth and Development
Age 0 to about Age 6
Day you were born, 98% of the baby are born upside down (head comes out first)
If the baby’s feet face down, and head is up, the delivery of the baby can be risky
https://en.wikipedia.org/wiki/Microcephaly
Gender of baby is determined by the presence or absence of the external genitals
Age 0 to age 6: brain continues to develop, head gets larger (malnutrition, accidents, injury to the head will affect brain growth and learning)
During this stage, bones are quite flexible and easy to break. The rest of the body grows steadily
After age 6, head size is steady (wont grow larger)
Pituitary gland (pea size) in the brain becomes active around age 10
(age 9 girls, age 11 for boys)
Age is not specific. This depends of diets, and race
Pituitary gland starts releasing growth hormones
(female: estrogen; male - testosterone) to wake body up and puberty starts gradually
This growth period will last for about 10 years (female, age 10 to 19; male age 11 to 20)
Diets: high meat, dairy diets - grow sooner
Diet: carbohydrates, vegetables/fruits - start later
