If a child has not started walking, and talking at age five, you don't need anyone to tell you something is wrong medically or otherwise.
Similarly, there are particular milestones you should reach at certain ages.
Don't let anyone fool you by convincing you that it's okay not to hit those milestones. Sure, everyone's time is different, but why must your own be late?
There are many opportunities you'll miss if you don't grab them at the right age. Know your age, and know the milestones you should be hitting.
