For a child, attachment is when the child begins to develop an attachment to the person who takes care of him regularly, that is, to whom he is closest. Generally speaking, children are most attached to their mothers when they are 8 to 9 months old, and if their mothers want to leave, they will cry and like to be held by their mothers. This means that the child has begun to form an attachment. This attachment reaches its peak at around 13 months of age. There are 3 main types of attachment 1. Safety type This type of child shows that the mother is next to the child, the child can play by himself for a while, he can crawl to find toys by himself, in the process of going, he will look back at his mother, and constantly communicate with her, using her as a safety base. 2.Avoidance type (or indifference type) This type of child shows no affection for his mother. These children seldom care about their mothers leaving, and most of the time they play by themselves. They automatically avoid interacting with their mothers when their mothers come back, and when their mothers hug them they will break away or physically move away, unwilling to look at their mothers and willing to play by themselves. He is even less avoidant of strangers than he is of his mother. 3.Conflicted type This type of child has a very contradictory attitude towards his mother, showing that he is very wary of her leaving and extremely distressed when she leaves, but when she comes back she shows conflicting emotions, being very close on the one hand, and then rejecting her angrily when she gets close, taking a lot of time to calm down, and then will cling to her even more, fearing that she will leave. Such children may cry for a long time when they are sent to kindergarten. The latter two types are insecure attachment types. What is the importance of secure attachment to the child’s future development? The establishment of secure attachment plays an important role in the infant’s later personality perfection in two ways: (1) The child’s tendency and ability to interact socially is good, and he or she has good conformity and flexibility to become a well adjusted person. (2) Children’s cognition, intelligence and creativity are maximized and may make themselves enterprising and intelligent. The above ideas are far-reaching and require careful consideration. The American psychologist Erikson suggested that the first stage of the model of a healthy personality (0 to 1 year) is the establishment of basic trust and basic distrust. If a child is given regular, unconditional care by the mother from birth, and responds to the needs of the child in a sensitive and accurate manner, such as feeding when hungry, letting the child sleep when sleepy, changing diapers when pooped, and hugging and kissing the baby when he or she needs your embrace, the child will feel secure and have a sense of trust in the caregiver. A person with a basic sense of trust grows up with the ability to believe in an ideal and faith. A person who has been loved by a mother (or another person other than the mother) knows how to love others, people, and the country. A child who does not build a secure attachment at an early age and does not make up for it later in development will grow up to be basically distrustful of others, always suspicious of others, always worried about being cheated by others, and lacking confidence in himself, becoming a weak person.
