Developmental Milestones at 9 months

• Major motor skills
• Fine motor skills
• Language
• Vision and hearing
• Social achievements and play
• When to be concerned

Major motor skills

Children in this age group should be able to sit independently on the floor for a period of 10–15 minutes. Often they can stand holding on to objects (e.g. coffee tables) for support, but cannot lower themselves. They will still take everything to their mouths. 

Fine motor skills

Fine motor movements should allow them to poke at a small pellet-sized object with their index finger. Their grasp should have developed such that they now use their finger and thumb in a scissor fashion.

Language

Children will often babble in long repetitive "strings" of syllables. 

Vision and hearing

Children should demonstrate rapid localisation of quiet meaningful sounds.

Social achievements and play

If an object falls, children should now attempt to look for it. They should be able to chew and feed themselves a biscuit. They should also be able to distinguish between familiar faces and strangers.

When to be concerned

Speak to your doctor if a nine-month-old child: 

• Does not appear interested in activities around them;
• Is not making eye contact or enjoying interaction;
• Is persistently difficult to settle;
• Seems anxious;
• Is not vocalising or making any sounds; or
• Does not appear to recognise their mother or close family.
