Child Development

This table gives an outline of the usual development of children with Down's syndrome. Just as with all children there is a great deal of individual variation in the age at which the different skills develop. In the table we show the usual range for some milestones. A few children will have additional health problems which may slow their development. However all will continue to develop at their own pace. You can use the table to find out if your child has particular difficulty in any area which may require extra help.
