Any function object that is a class attribute defines a method for instances of that class. It is not necessary that the function definition is textually enclosed in the class definition: assigning a function object to a local variable in the class is also ok.
Most children are born with very little arch in the feet. As they grow and walk, the soft tissues along the bottom of the feet tighten, which gradually shapes the arches of the feet. Children with flexible flatfoot often do not begin to develop an arch until the age of 5 years or older. Some children never develop an arch. If flexible flatfoot continues into adolescence, a child may experience aching pain along the bottom of the foot. A doctor should be consulted if a child's flatfeet cause pain.
A child's height and weight should be measured and marked on his or her growth chart as part of every visit to the doctor. Children under the age of 3 years should be measured at least every 6 months; children over 3, every year.If there is any concern about growth, measurements should be made as often as every 3 months until the growth pattern becomes clear.ost infants grow by as much as 10 inches (25.4 cm) and more than double their birth weight by their first birthday. Growth slows between 1 and 2 years of age. An average child grows about 5 inches (12 7 cm) between his or her first and second birthdays.
