To take account of the growth of the children for adequate bunk beds

The growth of the child under hears the increase in the size between the birth and the end of the adolescence of the various members of the organization. This is why for the clothes industry of the bunk beds and cupboards for children, it is necessary to take account of the growth of the latter. Especially, if it is considered that the growth of the child consists not only of one increase in the size, but also on the surface and volume of different the part of the body, the bodies, fabrics and in weight.
There exists however, several factors intervening in the process of the growth in the face and weight in the child. We can quote inter alia:
The food factors which justify the requirements in substances inserted into new fabrics, for example out of proteins for the synthesis of the bone or the muscle;
The hereditary factors which justify that the size of a child is always evaluated, according to the size of the parents to judge normality of it;
The hormonal factors are represented here especially by the growth hormone secreted by the pituitary gland, endocrine gland located at the base of the brain. The hormones of thyroid gland and the sex hormones intervene as well in maturation as in the growth.
Force is however to note that the growth of the child is done according to stages and at a well defined speed. So the normal growth proceeds in several phases each one presenting of the separately characteristics. Thus, it there with the growth of the first childhood which goes from 1 month up to 2 years; that of the second childhood goes from 2ans to 12 years and the last stage of the growth is that which marks puberty. However the speed of growth staturale, is the profit per year of size in centimetre, is for example very high in the infant (more than 20 centimetres the first year, nearly 10 the second).
Thus, the size, which is of approximately 50 centimetres to the birth, doubled at the 4 years age. The speed of growth is then decreased with 5 or 6 centimetres per annum and proportional to the age.
The swiftness of growth is then decreased with 5 or 6 centimetres per annum and proportional to the age. It decreases further with the puberty pre phase, then it undergoes a strong increase with puberty pulled by the effect of the sex hormones on the skeleton. A new reduction occurs in puberty phase post, reducing the growth to approximately 1 centimetre per annum approximately 3 years.
