Similar situation for me as well and he also 2.10 years old
From whatever you have explained... your kid seems to be fine.
Does he responds when his name is called? Eat all food?
Recognizes emotions? Adaptive for changes in routine?
if he fine with all above , i think its just matter of time.
However if you are so worried, just get an opinion from his pediatrician whther or not you need to start intervention.
Earlier the better...
Do not worry...
