This is considered when there is significant delay in a child reaching developmental milestones (i.e. sitting, crawling, standing or walking). Delay can occur in one or many areas—for example, motor, language, social, or thinking skills.
Although all children vary, the following list gives an indication of when motor activities are considered to be late and therefore intervention may be helpful.
- Unable to bring his/her hands together at 4 months
- Unable to roll over at 6 months
- Unable to control his/her head when pulled to a sitting position at 6 months
- Unable to sit independently (without support) at 8 months
- Unable to crawl at 12 months
- Unable to walk at 18 months
