At 9 months old, children reach various developmental milestones in social and emotional, language and communication, cognitive, and movement and physical domains. Here are some key milestones for a 9-month-old child:

Social/Emotional Milestones:

  • Is shy, clingy, or fearful around strangers
  • Shows several facial expressions, like happy, sad, angry, and surprised
  • Looks when you call her name
  • Reacts when you leave (looks, reaches for you, or cries)
  • Smiles or laughs when you play peek-a-boo.

Language/Communication Milestones:

  • Makes a lot of different sounds like “mamamama” and “bababababa”
  • Lifts arms up to be picked up

Cognitive Milestones:

  • Bangs two things together

Movement/Physical Development Milestones:

  • Gets to a sitting position by herself
  • Moves things from one hand to her other hand
