Most human babies demonstrate an innate swimming or diving reflexfrom birth until the age of approximately six months, which are part of a wider range of primitive reflexesfound in infants and babies, but not children, adolescents and adults. Other mammals also demonstrate this phenomenon (see mammalian diving reflex).
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]

The ossification of the cuboid occurs reliably at 37 weeks gestation and its appearance is often used as a marker of foetal maturity. At birth of a ‘full-term’ baby the average foot length is 7.6 centimetres (range 7.1 – 8.7 cm).
The Maturational Theory of child development was introduced in 1925 [1] by Dr. Arnold Gesell, an American educator, pediatrician and clinical psychologist whose studies focused on "the course, the pattern and the rate of maturational growth in normal and exceptional children" (Gesell 1928). [2] Gesell carried out many observational studies ...
