What You Need to Know

At 8 months, babies are rapidly developing various skills. They typically show noticeable growth in their ability to interact with their environment, communicate, and form social connections. Recognizing these developmental milestones can help parents and caregivers support their child’s growth effectively.

Evidence-Based Guidelines

According to the Centers for Disease Control and Prevention (CDC), key developmental milestones for an 8-month-old include:

  • Physical Development: Babies should be able to sit without support, which reflects strong muscle development. They may also start crawling or scooting.
  • Cognitive Development: Infants at this age can transfer objects from one hand to another and may show interest in exploring their surroundings.
  • Language Development: The American Academy of Pediatrics (AAP) highlights the importance of babbling and responding to their name as signs of language growth.
  • Social-Emotional Development: Around this age, babies may exhibit fear of strangers, indicating the development of attachment and social skills.

WHO guidelines emphasize the importance of interactive play, which significantly enhances cognitive and social development in infants under 1 year. Engaging with your baby through play can foster their natural curiosity and support their learning.

Common Questions Parents Ask
