Montessori referred to the sensitive period is out of a profound impact on the concept. Ago when we took the kids will find a number of phenomena, but do not know of these phenomena is called the sensitive period, would not know the sensitive stage in the education above, there are so far-reaching impact. From birth to grow up, there are many segments of the sensitive period, in the future will be "sensitive understanding of the various stages of children" speak in detail. 

Where the first give one or two examples, simply explained. When God created the child, give each child a different stage of development the sensitive period. In about one year old child will be very carefully to see what little things on the ground, even a small ball of wool, a paper clip, a small grain of rice, he will pick it up, and then stuffed into his mouth to lick see. I believe many people know that when the mother's children have such a phenomenon, but do not know the meaning behind it. More than one year old child why have these small things so sensitive it? Because he came from the observation of these small things about the world. 

As for the two-year-old child, he had a sensitive period of order, this time the children want the environment to remain in his familiar position: a daily walk of the line should be the same, the order to the same bath, dining table seats to the same thing To put the same place .... Because children at this stage to rely on this way to establish order in his life, and if there are too many changes in life, he would feel very uncomfortable. Year-old children will not like, five years old children would not be so wonderful is that once out of that sensitive period, he would not be so upheld. Therefore, the sensitive period in the order of the children, if any changes need to do, should be informed in advance, to his mental preparation, otherwise the problem unilaterally adults, because you do not understand his need for it! If you get to know and he can peacefully exchange between parents and children will be more smooth.
