Keeping in mind that all children are different to begin with and that a impaired child may take more time to reach these levels, it is good to know what a "normal" child development looks like.
There are many charts and lists out there that say where your child should be in their development at any given point in their life. I will list the milestones from the chart I was given from the "Early On" program.
This is the child development milestone chart i am using to watch my son.

As said before, not all children are perfectly average in every aspect. Some will reach these developmental milestones before others and some may take a bit longer.
Having a child with the possibility of developmental issues just means you have to pay more attention to these milestones to give your child the help they may need in reaching them.
