Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2]
Gestational age: 12 weeks and 0 days until 15 weeks and 6 days old. Embryonic age: 10 weeks and 0 days until 13 weeks and 6 days old. The fetus reaches a length of about 15 cm (6 in). A fine hair called lanugo develops on the head. Fetal skin is almost transparent. More muscle tissue and bones have developed, and the bones become harder.
For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates – infants weighing less than 2,500 g (5 lb 8 oz) – are small for gestational age. [citation needed] There is an 8.1% incidence of low birth weight in ...
There is no sharp limit of development, gestational age, or weight at which a human fetus automatically becomes viable. [13] According to studies between 2003 and 2005, 20 to 35 percent of babies born at 23 weeks of gestation survive, while 50 to 70 percent of babies born at 24 to 25 weeks, and more than 90 percent born at 26 to 27 weeks ...
An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
