In order to prevent developmental abnormalities in at-risk children, parents should give scientific guidance on anticipatory interventions for psycho-behavioral development based on the characteristics of children’s psycho-behavioral development, according to the principle of individualization and focusing on the characteristics of continuity and stages of development. Neonatal period 1. Emphasize the importance of mother-infant communication and encourage parents to have more contact with their newborns, such as talking, smiling and embracing. 2.Learn to recognize the cries of newborn infants, soothe their emotions and meet their needs in time, such as breastfeeding on demand. 3.Newborns can be practiced in prone position one hour after feeding, and passive baby exercises can be performed one to two times a day. 4. Touch the newborn, let the newborn see faces or brightly colored toys, listen to pleasant bells and music, etc., to promote the development of their sensory perception. 1～3 months 1.Focus on parent-child communication, talk and tease with the baby with emotion more during feeding and nursing, respond to the baby’s voice with a smile, voice or nod, and emphasize eye contact. 2.Exercise the infant’s head and neck movement and control ability through prone, vertical holding exercises, passive exercises, etc. 3.Increase moderate auditory, visual and tactile stimulation, listen to pleasant music or toys with loud sounds, and use brightly colored toys to attract infants’ attention and tracking. 3～6 months 1.Encourage parents to raise their babies themselves, take the initiative to identify and respond to the physical and psychological needs of their babies in a timely and effective manner, and gradually establish a secure parent-child attachment. 2.Cultivate regular eating and sleeping habits, and play more parent-child games such as looking in the mirror, hide and seek, and find the source of sound with infants. 3.Create a rich language environment, talk more with the infant, imitate the infant’s voice to encourage the infant’s pronunciation and achieve the purpose of “communication response”. 4. Encourage infants to roll over freely and practice sitting properly; let infants reach out more to grasp toys and objects of different textures to promote the development of hand-eye coordination. 6～8 months 1.Parents should accompany and pay more attention to their infants, expand the scope of their activities under the condition of ensuring their safety, and encourage contact with the outside environment and people. 2.Frequently call the baby’s name and say the names of objects at home to develop the baby’s ability to understand language. Guide infants to pronounce “ba ba” and “ma ma” to increase their interest in pronunciation. 3.Help infants practice sitting alone and crawling, jumping under the armpits; practice reaching for distant toys, passing toys with both hands, tearing paper and other hand coordination and finger grasping actions to improve hand-eye coordination. 8～12 months 1.Help infants to recognize the different expressions of others; divert their attention when they are angry, bored, unhappy and other negative emotions; give encouragement and support when they are frustrated. 2.Enrich the infant’s language environment, often talk to the infant and look at pictures. Let infants make actions and expressions according to instructions, such as answering to names and waving “goodbye”. 3.Help infants practice crawling on their hands and knees and learn to stand and walk while holding objects; provide infants with safe toys such as cups, blocks and balls to develop hand-eye coordination and relatively accurate manipulation skills. 4. Increase imitative games, such as clapping “welcome”, pinching toys with loud sounds, patting dolls, dragging blankets to obtain toys, etc.
