So what exactly is a So what exactly is a developmental delay?developmental delay?
What is a What is a developmental delay?developmental delay?
Not a specific condition. Not a specific condition. A A A A lag in developmentlag in development or or slower rate of slower rate of
developmentdevelopment in which a child exhibits a in which a child exhibits a functional level below functional level below
the norm for his agethe norm for his age
Are there different Are there different types of developmental types of developmental delay ?delay ?

So how do we handle parents So how do we handle parents questions pertaining to questions pertaining to development ????development ????
Why is my child not reaching Why is my child not reaching his milestones ?his milestones ?
Development is individual to each child
Acceptable variation of 1-2 months on either side of the normal expected age to attain milestones
Several factors may impact on the child development
If your child is delayed need to identify the cause and address the problem as soon as possible
Often hard to make a formal diagnosis during the first two years of life. Signs are often transient e.g. late bloomers
Milestones not as important as the quality and sequencing of movement
“ “ Late bloomer”Late bloomer”
No suspicious birth No suspicious birth historyhistory
No obvious No obvious neurological pathologyneurological pathology
Positive family history Positive family history of achieving of achieving milestones later than milestones later than expectedexpected
Normal components of Normal components of movement are presentmovement are present
No indication as to No indication as to why child delayedwhy child delayed
Eventually Eventually completely completely

My child is not walking My child is not walking yet, so can I use a yet, so can I use a walkingwalking ring? ring?

Tethered cord Tethered cord syndromesyndrome Early stages of a pregnancy, the spinal cord of the Early stages of a pregnancy, the spinal cord of the
