9 Month Old Baby

Around nine months

What this month often looks like

  • Around this age many babies are shy or clingy with strangers and show many facial expressions.
  • Some look when their name is called, babble, and sit without support.
  • Many move things from one hand to the other.

How your baby is developing

  • Nearer nine months many babies sit without support, though the age this arrives at varies widely.
  • Sitting can still end suddenly, and that is not a setback.
  • Banging two objects together is something many babies begin doing around nine months.
  • The same movement can look accidental one day and decided the next.
  • Looking for an object that has dropped out of sight is something many babies do around nine months.
  • Looking in the right place is a different skill from looking.
  • Making a lot of different sounds, including repeated strings like "mamama" or "bababa", is common around nine months.
  • Looking up when their name is called becomes more consistent for many babies around this age.
  • Lifting their arms up to be picked up is something many babies do around nine months.
  • Reacting when a familiar adult leaves, and watching unfamiliar people carefully, are common around this age.

Everyday care and connection

  • Safe floor space matters more than any seat or support device.
  • Two safe objects that make a sound when they meet are usually all this game needs.
  • Peekaboo covers the same idea with a face instead of a toy, and needs nothing at all.
  • Point at what you are both looking at and say its name — sharing attention is what gives a word somewhere to land.
  • Saying you are going and coming back, every time, is more useful than slipping away quietly.

How you may be feeling

  • More movement can mean feeling constantly alert — and tired.
  • That is understandable.
  • Comparing notes with another parent is easier when you remember how different two babies the same age can be.
  • Noise is part of the appeal, not a side effect.
  • Anticipating the moment a face returns is its own small pleasure.
  • Repeated syllables are practice with sound, not yet words with meaning attached.
  • Being more attached and more wary of strangers at the same time is a familiar pairing, not a problem to fix.

Something that may help

Sharing the load and resting when you can really helps.
