Signs of Global Developmental Delay Some of the first signs of developmental delay are a lack of developing or achieving milestones lower than other children for example in learning how to sit, crawl or walk. Don't worry, not all delays are significant as children develop and learn at their own rate. If you are worried come and see one of our specialist physiotherapists who can assess and treat any developmental delays. Global Developmental Delays can show reduction in all areas of development and early intervention is key for these children to assist them in reaching their milestones and achieving their full potential.
