These scores are used to determine the child's performance compared with norms taken from typically developing children of their age (in months). [1] The Bayley-III has three main subtests; the Cognitive Scale, which includes items such as attention to familiar and unfamiliar objects, looking for a fallen object, and pretend play, the Language ...
Newborns typically lose 7–10% of their birth weight in the first few days, but they usually regain it within two weeks. [17] During the first month, infants grow about 1 to 1.5 inches (2.5 to 3.8 cm) and gain weight at a rate of about 1 ounce (28 g) per day. [17] Resting heart rate is generally between 70 and 190 beats per minute. [18]
Starting in 2003, women have also been able to use a three-month version of the pill. [54] Similar to the effect of using a constant-dosage formulation and skipping the placebo weeks for three months, Seasonale gives the benefit of less frequent periods, at the potential drawback of breakthrough bleeding. Seasonique is another version in which ...
The first permanent birth-control clinic was established in Britain in 1921 by Marie Stopes working with the Malthusian League. [171] The clinic, run by midwives and supported by visiting doctors, [172] offered women's birth-control advice and taught them the use of a cervical cap. Her clinic made contraception acceptable during the 1920s by ...
Different terms are used to describe prenatal development, meaning development before birth. A term with the same meaning is the "antepartum" (from Latin ante "before" and parere "to give birth") Sometimes "antepartum" is however used to denote the period between the 24th/26th week of gestational age until birth, for example in antepartum ...
The speed of physical growth is rapid in the months after birth, then slows, so birth weight is doubled in the first four months, tripled by 1 year, but not quadrupled until 2 years. [85] Growth then proceeds at a slow rate until a period of rapid growth occurs shortly before puberty (between about 9 and 15 years of age). [86]
It is thought to have some protective roles during fetal development and for a few hours after birth. The second stage varies from one woman to another. In first labours, birth is usually completed within three hours whereas in subsequent labours, birth is usually completed within two hours. [59]
The first stage of development runs from birth to 18 months and thus covers the infancy period. The conflict which Erikson identified during this time was trust vs mistrust. During this vulnerable point in the child's life, they are faced with uncertainties in the world and are therefore reliant on their caregiver.
