Physical Characteristics
- Height and weight increase significantly during infancy.
- Head circumference is an important indicator of brain development.
Nutritional Needs
- Breastfeeding is essential for infants.
- Weaning is a critical aspect of infant nutrition.
Teething Pattern
- Teething typically follows a specific pattern.
Brain Maturation
- Head control is a reliable indicator of brain maturation.
- The anterior fontanel (diamond-shaped) closes by 12-18 months of age.
- The posterior fontanel (triangle-shaped) closes by 8 weeks (2 months) of age.
Developmental Milestones
- 1 Month:
- Head lag (poor head control)
