Physical development. Typically grows at a similar rate to the previous month, usually growing between 1 and 1.5 inches (2.5 and 3.8 cm) and gaining about 2 pounds (910 g). [23] Resting heart rate is usually between 80 and 160 beats per minute, and it typically stays within that range until the infant is about one year old. [18] Motor development
The speed of motor development is rapid in early life, as many of the reflexes of the newborn alter or disappear within the first year, and slows later. Like physical growth, motor development shows predictable patterns of cephalocaudal (head to foot) and proximodistal (torso to extremities) development, with movements at the head and in the ...
