Worrying about DCD in a 9–12-month-old

If you're watching your baby and wondering whether their movements seem a little behind, that careful, loving attention is exactly right — and the honest answer brings real relief.

In short

At 9–12 months, it is too early to diagnose Developmental Coordination Disorder (ICD-11 6A04). DCD is a diagnosis about how a child learns and performs coordinated motor skills — and that simply cannot be judged in a baby who is still acquiring their very first movements. The label is usually only considered from around age 5 and above, once a child has had a fair chance to learn skills like dressing, drawing or using cutlery. So please set the worry about DCD specifically gently aside. What is right at this age is simply to watch your baby's motor milestones and share any concerns at a routine check.

What is actually worth watching at 9–12 months

Rather than looking for DCD, observe the broad gross-motor milestones appropriate to this window. Most babies around this age:

• Sit steadily without support
• Move themselves — crawling, bottom-shuffling, rolling or pulling to stand
• Pull up to stand holding furniture, and may begin cruising
• Use both hands — passing toys hand to hand, picking up small items with finger and thumb
• Bear weight on legs when held standing

Remember that healthy babies vary widely, and some skip stages (a baby who shuffles instead of crawling can be perfectly typical). A premature baby should be measured against their corrected age.

When to mention it sooner

Have a calm word with your paediatrician — not because of DCD, but as a sensible developmental check — if by around 12 months your baby:

• Cannot sit without support, or feels persistently very floppy or very stiff
• Is not bearing any weight on their legs when held
• Uses only one side of the body, or always favours one hand (a strong hand preference this early is worth checking)
• Has clearly lost a skill they once had

These are simply prompts for a friendly check, not signs of any one condition.
