The timing of milestones varies from child to child.  Many children will achieve the milestones before or after the 'average' ages. Achieving fine motor milestones a little early may be of no consequence or may indicate that a child is going to be particularly dexterous. However, achieving these milestones a little late has probably no significance whatsoever. A more significant delay may in a few cases suggest that there is an underlying problem.

If you have any concerns, consult your pediatrician. Below is a list of "average" milestone ages. These are merely averages that have been noted, these are not set in stone.

There is a lot of information available online and through pediatric associations. Ask you caregiver if you're concerned about your child's development, but remember that these are suggested stages and every child learns and grows at his or her own pace. It is not recommended you force your child to do anything. Introduce new skills to them so that they can learn from you but remember to be patient.
