What You Need to Know

Tracking your baby's development can seem overwhelming, but it is essential for ensuring their growth is on track. Developmental milestones are indicators of how your baby is progressing in various areas such as motor skills, social interactions, and communication. The American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC) provide guidelines that can help parents understand these milestones and when to seek help if needed.

Evidence-Based Guidelines

The CDC recommends that parents track developmental milestones and schedule regular screenings for their children at 9, 18, and 24 months. These screenings help detect any potential developmental delays early on, facilitating timely intervention. According to the AAP, by 2 months, babies should show signs of social engagement, such as smiling and making eye contact. By 6 months, most babies can sit with support and begin to babble. By the time they reach 12 months, they may be able to stand with support and say simple words like "mama" or "dada".

Developmental Milestones

  • 0-2 Months: Begins to smile at people.
  • 2-4 Months: Can hold a toy and shake it, follows moving things with eyes from side to side.
  • 4-6 Months: Can roll over in both directions, begins to sit without support.
  • 6-9 Months: Can stand, holding on, and can look for things he sees you hide.
  • 9-12 Months: Can take a few steps without holding on and can say "mama" and "dada".
