General characteristics[edit | edit source]
The characteristics of a full term baby are:
- Average weight of 3500g
- Average length of 50cm
- Well developed external genitalia; testes in scrotum and labia majora covering labia minora
- Remnants of lanugo hair on back
- Nails extending beyond tips of fingers and toes
Length of pregnancy is from the 1st day of the last menstruation up until approximately 280days (i.e. 10 lunar months). Or in other terms, approximately 266 days after fertilization. During this time certain check-ups on the fetus are carried out so as to check for healthiness and identification of any problems that may exist.
