Agree with Ayesha.Don't beat to make him learn.beating will create more pressure on him to remember name of things & out of fear he will again forget.Whenever he says correct answer clap , say very good or excellent & encourage him more to say correct & don't mind when he gives wrong answer.Automatically he will learn names of those things which he doesn't know & his confusion will also go gradually as he grows he is still below 3 so always don't expect correct answers .

Spend time with him play some interesting game like coloring, make toys from clay dough, dance etc

First stop the habit...
Too much of screen time is not good for his eyes...
Explain him clearly that how it harms...at this age,he can understand your words...

If he doesn't listen,

Hide the mobile,you too don't use the mobile whenever he is with you...

And give only one hour time to watch,tell like TV is not working...

There are many activities which he can do playing, writing,reading,painting,drawing, puzzling...give some work to him...

Teach him the syllabus of present standard...
You can also Google for the activities....

Hi can you send image of previous reports?

Y r u watching such things during pregnancy which r giving u stress.Please avoid such tv programmes which r making u emotional or make u cry.Ur negative or sad emotions will have same effect on baby .

Hi that's normal don't worry

Hi it might be due to tear duct blockage which is normal in babies and massage baby's side of the nose from up to down 2-3 times a day it will clear the blockage

It's bcoz of his age.He must b feeling left out , not able to tolerate suddenly someone smaller than him getting attention them him.Stop mobile completely, bring new toys for him , new dresses,if u r in joint family ask anyone to look after baby for sometime when baby not sleeping.Its bcoz of frustration he is behaving like that.Remember to keep patience with him always even if he appears irritating, scolding may make him more frustrated
