The first year of infancy: the most rapid period of development

The first year of a baby's life is the period of most rapid development, which can be physiologically divided into three stages: 0–1 and 0–1.coarse movements(such as lifting the head, rolling over, sitting, crawling) andfine movements(Such as grasping, pinching objects with fingers) are the two main categories. During this period, the baby also begins to establish an emotional connection with the caregiver and expresses their needs through voice, facial expressions and body language.

Physiological motor development (gross motor skills and fine motor skills)

Development Reference

The following are common references for observing the age of infants.This is for trend awareness purposes only and does not imply that "failure to meet the standard is abnormal".：

• 1 month:It will stare at people's faces.
• 2 months:It can be amusing.
• 3 months:It might laugh out loud.
• 4–5 months:She began to recognize strangers and showed a friendly smile to her mother.
• 6 months:They will put food in their mouths by themselves, or open their mouths to indicate that they want more food.
• 7– 8 months:Perhaps she smiles at her reflection in the mirror.
• 9–10 months:When you reach out for a toy, he might hand it to you; or he might start to fear strangers.
• 12 months:They can point out what they want.

Motor development is a continuous process, and most babies will gradually master it over a period of time, without needing to compare themselves with other babies.

Psychological and Emotional Development

In terms of emotional regulation and interpersonal interaction, babies will gradually develop: smiling at people, opening their mouths to indicate that they want more food when they are full, and pointing to what they want; and expressing different emotions and needs through sound and facial expressions.

約 Around 6 months oldBabies begin to develop an attachment to their closest caregivers. Research indicates that the brain grows rapidly from 25 weeks of gestation to two years after birth (especially the right brain), and this expansion is directly influenced by the richness of the early environment and social interaction experiences; the emotional experiences babies gain from sounds, images, and interactions form the foundation for early learning.

The timing of starting also depends on whether the baby shows signs of readiness (such as being able to sit steadily, showing interest in food, and the disappearance of the tongue thrust reflex).Please refer to the pediatrician's assessment and your baby's individual condition.It is not advisable to do it too early.
